ʻO ka poloka terminal wili PCB J-GUANG - moʻo pitch 5.0mm no nā kauoha nui

Ke kau nei kahi hui kūʻai i kahi kauoha nui no nā poloka terminal—e ʻōlelo i 50,000 mau ʻāpana o ke ʻano wili PCB pitch 5.0mm—ʻaʻole lākou e hilinaʻi wale i ka pepa ʻikepili. Hoʻouna lākou i nā mea loiloi, noi i nā laʻana, a holo i nā hoʻāʻo e ʻoi aku ma mua o kahi nānā maka maʻalahi. Ma J-GUANG, ua hoʻokipa mākou i nā ʻumi o nā loiloi hale hana i nā makahiki he ʻumi i hala iho nei, a ua ʻike mākou i nā ʻano nānā koʻikoʻi like e kū mai ana ma nā ʻoihana: mai nā mea kūʻai aku automation ʻoihana ma Kelemania a hiki i nā OEM hāʻawi mana ma ʻAmelika ʻĀkau. Wehewehe kēia ʻatikala i nā kiko loiloi pololei e hoʻohana ai nā hui kūʻai ma mua o ka hāʻawi ʻana i ka ʻae hale hana no nā kauoha nui poloka terminal, ma muli o kā mākou ʻike mua a me nā kūlana ʻoihana e like me IEC 60998 a me UL 1059.

Inā he loea kūʻai ʻoe e ʻimi nei e hoʻomaʻemaʻe i kāu papa inoa loiloi a i ʻole he mea hana e manaʻo ana e hala i nā nānā ʻana ma ka hoʻāʻo mua ʻana, uhi nā ʻāpana ʻehiku ma lalo nei i ka hōʻoia ʻana o nā mea, ka hoʻokō ʻana i nā ana, ka hoʻāʻo uila, ka pono o ka plating, ka hōʻoia ʻana i ka hoʻopili ʻana, ka loiloi palapala, a me ka hiki ke hana ma kahi. E hoʻokomo mākou i ka ʻikepili maoli mai kā mākou laina hana ponoʻī—e like me ka Poloka hope wili PCB 301-5.0—e wehewehe i nā mea i hala a me nā mea i hāʻule. E hoʻomaka kākou me ke kumu: ka hōʻoia ʻana i nā mea.

1. Nānā Kūlike o ka Palapala Hōʻoia Mea: Ma ʻō aku o ke Kāleka Melemele UL

ʻAʻole ʻae nā hui kūʻai i kahi kāleka melemele UL ma ke kumukūʻai maka. Ke koi nei lākou i nā hōʻike hoʻāʻo mea kikoʻī (MTR) no kēlā me kēia ʻāpana resin i hoʻohana ʻia ma ka hale poloka terminal. No kā mākou mau hale PA66, ʻo ia hoʻi ka hōʻoia ʻana i ka helu lapalapa UL 94 V-0 me ka ʻikepili hoʻāʻo puhi maoli: pono ka manawa afterflame ma lalo o 10 kekona no kēlā me kēia specimen, a ʻaʻohe kulu puhi e hiki ke hoʻā i ka hōʻailona pulupulu. Ua ʻike mākou i nā loiloi e hōʻole ana i kahi batch no ka mea ua hōʻike ka MTR i kahi afterflame 12 kekona ma kekahi sample—ʻoiai ʻo ka awelika he 8 kekona. ʻO ke kūlana maʻamau no kēlā me kēia specimen, ʻaʻole ka awelika.

Ma waho aʻe o ka lapalapa ʻana, nānā lākou i ka ʻike o ke aniani fiber i loko o ka PA66. ʻO ka kikoʻī maʻamau he 30% ±2% ka hoʻopiha aniani no ke kūpaʻa dimensional. Hoʻohana nā mea loiloi i ka loiloi thermogravimetric (TGA) e hōʻoia i kēia. Inā hāʻule ka ʻike o ke aniani i 27%, hiki i ka hale ke warp i ka wā o ka hoʻopili ʻana i ka nalu, e hana ana i ka misalignment pin. Mālama mākou i ka hiki TGA i loko o ka hale e hōʻoia mua i kēlā me kēia pūʻulu ma mua o ka hoʻouna ʻana. No ka metala terminal, noi nā hui kūʻai i kahi loiloi spectrographic e hōʻoia i ka haku mele keleawe (maʻamau ʻo C36000 a i ʻole C37700) me ka ʻike keleawe ma luna o 57% a me ka ʻike kēpau ma waena o 1.5% a me 3.5% no ka machinability. Hāʻawi mākou i kēia ʻikepili i loko o kā mākou palapala huahana no kēlā me kēia kauoha nui.

Nā keʻena hoʻokolohua waho e like me Nā lawelawe hoʻāʻo mea a UL hoʻohana pinepine ʻia no ka hōʻoia ʻana o ka ʻaoʻao ʻekolu. Hiki i nā hui kūʻai ke noi aku i kahi hōʻike hoʻāʻo i hōʻoia ʻia e ISO 17025 mai ka lab o ka mea hoʻolako. Ma J-GUANG, paʻa mākou i ka palapala hōʻoia ISO 9001:2015 a mālama i nā moʻolelo calibration no nā lako hoʻāʻo āpau, kahi a nā mea loiloi e nānā ai i ka wā o ka hele ʻana o ka hale hana.

2. Hoʻokō Ana ma lalo o ka Microscope: ʻO ke kānāwai 0.1mm

ʻO ka nānā ʻana i nā ana kahi e loaʻa ai ka hapa nui o nā loiloi kauoha nui. Hoʻohana nā hui kūʻai i nā mīkini ana hoʻonohonoho (CMM) a i ʻole nā ​​​​mea hoʻohālikelike optical e nānā i nā ana koʻikoʻi ma kahi nui o ka laʻana o 125 mau ʻāpana no ka lot (e like me IEC 60512-1). No kahi poloka terminal pitch 5.0mm, ʻo nā ana koʻikoʻi: ka mamao o ka pitch (5.0mm ± 0.2mm), ke anawaena pine (1.0mm ± 0.05mm), ka lōʻihi holoʻokoʻa (10.0mm ± 0.3mm), a me ka offset kikowaena lua (≤0.1mm). Ua ʻike mākou i nā loiloi e hōʻole ana i kahi puʻupuʻu no ka mea ʻo ke anawaena pine ma 3 mai 125 mau laʻana i ana ʻia he 0.94mm—0.01mm wale nō ma lalo o ka palena kikoʻī haʻahaʻa. He paʻa loa ka hoʻomanawanui.

Akā, ʻo ka nānā pono ʻana ma ka pilina pili: ka hohonu o ke kaula wili a me ka wehe ʻana o ke kaula uea. No kā mākou kumu hoʻohālike 301-5.0, pono ka hohonu o ke kaula wili M2.5 he 4.0mm ±0.1mm, a ʻo ka wehe ʻana o ke kaula uea he 2.5mm ±0.15mm. Hoʻohana nā mea loiloi i nā ana hele/ʻaʻole hele no kēia mau nānā. Inā pāpaʻu loa ka hohonu o ke kaula, ʻaʻole e hāʻawi ka wili i ka ikaika paʻa kūpono no ka uea 14 AWG; inā hohonu loa, hiki i ka wili ke hāʻule i lalo a hemo. Ua hōʻuluʻulu mākou i kahi papa hoʻohālikelike mai kā mākou mau moʻolelo loiloi e hōʻike ana i nā helu hala/hāʻule maʻamau:

Mālama mākou i kahi ʻōnaehana kaohi hana helu (SPC) e hahai ana i kēia mau ana i ka manawa maoli i ka wā o ka hoʻoheheʻe ʻana i ka injection a me ka stamping. Makemake nā mea loiloi e ʻike i nā pakuhi SPC—hōʻike ia he proactive mākou, ʻaʻole reactive. No ka ʻike hou aku e pili ana i kā mākou kaʻina hana maikaʻi dimensional, e nānā i kā mākou ʻike kikoʻī o ka laina huahana.

3. Hoʻāʻo Uila ma lalo o ke Kaumaha: Kūpaʻa Dielectric a me ke Kūʻē Hoʻopili

ʻAʻole hoʻāʻo wale nā ​​​​kime kūʻai i nā poloka terminal ma ka mahana o ka lumi. Hoʻāʻo lākou ma nā mahana kiʻekiʻe (85°C no 1000 mau hola e like me IEC 60998-2-1) a ma hope o ka hōʻike ʻana i ka haʻahaʻa (95% RH no 48 mau hola). ʻO nā ʻano uila koʻikoʻi ʻelua, ʻo ia ka volta dielectric resistant a me ke kū'ē pili. No kahi poloka terminal i helu ʻia he 300V, ʻo ka hoʻāʻo dielectric he 1500V AC no 1 minuke me ka ʻole o ka haki a i ʻole ke kahe ʻana o ke au e ʻoi aku ma mua o 5mA. Ua ʻike mākou i nā mea loiloi e hoʻopili ana i ka 1800V no 5 kekona ma ke ʻano he hoʻāʻo margin—inā hāʻule, ua hoʻokaʻawale ʻia ka ʻāpana holoʻokoʻa.

Ana ʻia ke kū'ē pili me ka hoʻohana ʻana i ke ʻano hana Kelvin ʻehā-uea. ʻO ka kikoʻī maʻamau he ≤5 milliohms mua, a he ≤10 milliohms ma hope o 50 mau pōʻaiapuni hoʻokomo/hoʻihoʻi. Akā eia ka pilikia: hoʻāʻo pinepine nā hui kūʻai me ke uea maoli (14 AWG keleawe i wili ʻia) ma mua o kahi pine hoʻāʻo, no ka mea, ʻo ka pilina uea-a-terminal ka mea nui ma ke kahua. Inā lawa ʻole ka ikaika o ka hoʻopaʻa ʻana o ka wili, hiki i ke kū'ē pili ke piʻi aʻe i 20 milliohms ma hope o ka hoʻomehana wela. Hoʻāʻo mua mākou i kēlā me kēia pūʻulu me kahi au 10A no 1000 mau pōʻaiapuni e hōʻoia i ke kūpaʻa. E like me nā labs waho ʻO nā lawelawe hoʻāʻo uila ʻo TÜV Rheinland e hāʻawi i ka hōʻoia kūʻokoʻa no nā mea kūʻai e pono ai.

ʻO kekahi loiloi a mākou i mālama ai i ka makahiki i hala e pili ana i kahi hui kūʻai mai kahi mea hana inverter solar. Ua lawe mai lākou i kā lākou mea hoʻāʻo ponoʻī a holo i kahi hoʻāʻo dielectric 2000V ma 50 mau laʻana. Ua hala nā mea a pau, akā ua ʻike lākou ua ana ka mamao creepage ma kā mākou kumu hoʻohālike 301-5.0 i 6.2mm—ma luna o ka palena iki o 5.5mm no ka haumia 300V kekelē 2. ʻO kēlā palena keu i loaʻa iā mākou kahi kūlana mea hoʻolako makemake ʻia. ʻAʻole wale ka hoʻāʻo uila e pili ana i ka hala/hāʻule; e pili ana i ka hōʻike ʻana i ka paʻa o ka hoʻolālā.

4. Ka Pono o ka Plating a me ke Kū'ē ʻana i ka ʻAʻai: ʻO ka ʻoiaʻiʻo o ka pīpī paʻakai

ʻO nā kikowaena poloka terminal he keleawe i uhi ʻia me ka nickel, me ka mānoanoa o ka plating he 2-5 microns. Hōʻoia nā hui kūʻai i kēia me ka hoʻohana ʻana i nā mea kālailai fluorescence X-ray (XRF). Inā ma lalo o 2 microns ka papa nickel, hiki i ka terminal ke pala i nā wahi haʻahaʻa kiʻekiʻe, e alakaʻi ana i ka hoʻonui ʻana i ke kū'ē ʻana i ka pili. Ua ʻike mākou i nā mea loiloi e hōʻole ana i kahi pūʻulu kahi i ʻōlelo ʻia ai ka mānoanoa nickel awelika he 1.8 microns—ʻoiai ua ʻōlelo ka spec he 2-5 microns. ʻO ka palena haʻahaʻa loa ia.

Akā ʻo ka hoʻāʻo maoli ka pīpī paʻakai e like me ASTM B117. No nā poloka terminal ʻoihana, he 48 mau hola o ka pīpī paʻakai me ka ʻole o ka popo ʻulaʻula ma ka ʻili terminal he mea maʻamau. Pono kekahi mau kikoʻī papa kaʻa i 96 mau hola. Hana mākou i nā hoʻāʻo pīpī paʻakai ma kēlā me kēia ʻāpana hana a hāʻawi i ka hōʻike. I ka wā o hoʻokahi loiloi, ua noi kahi hui kūʻai mai kahi hui uila moana i 120 mau hola pīpī paʻakai—ua ʻae mākou me ka ʻole o ka pala, akā no ka mea wale nō i loko o kā mākou kaʻina hana plating kahi papa lalo nickel o 3 microns ma mua o ka hoʻopau nickel hope loa. ʻO kēlā mānoanoa keu ke kumukūʻai iā mākou ma kahi o $0.002 no kēlā me kēia terminal, akā kūpono ia no ka ʻae ʻia.

Nānā pū nā mea loiloi i ka hoʻopili ʻana o ka plating me ka hoʻohana ʻana i kahi hoʻāʻo lipine (ASTM D3359). Inā hemo kekahi plating, e hōʻole ʻia ke kikowaena. Ua hoʻomaikaʻi mākou i kā mākou kemika ʻauʻau plating e hōʻoia i ka hoʻopili ʻana, a hoʻopaʻa mākou i ka haku mele ʻauʻau a me ka mahana no kēlā me kēia neʻe ʻana. No ka ʻike hou aku e pili ana i kā mākou kaʻina hana plating, e ʻike i nā kikoʻī loea ma kā mākou ʻaoʻao huahana.

5. Hōʻoia ʻana i ka Pūʻolo: ʻAʻole wale nō he Pahu

Pono nā kauoha nui o 50,000 mau poloka terminal e pono ai ka ʻōpala e pale ai i ka hōʻino ʻia i ka wā o ka hoʻouna ʻana a me ka mālama ʻana. Nānā nā hui kūʻai i ka ʻōpala no ʻekolu mau mea: ka pale anti-static, ka pale makū, a me ka cushioning mechanical. He hygroscopic nā poloka terminal me nā hale PA66—inā i hōʻike ʻia i ka >60% RH no nā hola he 48 a ʻoi, hiki iā lākou ke omo i ka makū a hana i nā hemahema soldering (popcorning) i ka wā o ka soldering nalu. Nānā nā mea loiloi aia i loko o ka ʻōpala kahi ʻeke pale makū me ka desiccant a me kahi kāleka hōʻailona makū. Inā hōʻike ke kāleka i ka poni (e hōʻike ana i ka >60% RH), ua hōʻole ʻia ka hailona holoʻokoʻa.

Ua hōʻoia ʻia ka hoʻoluʻu mīkini me ka hoʻohana ʻana i nā hoʻāʻo hāʻule: ua hāʻule kahi pahu o nā poloka terminal mai 1.2 mika ma luna o kahi papahele sima. Inā ʻoi aku ma mua o 1% o nā ʻāpana e hōʻike ana i nā hale i haki a i ʻole nā ​​pine kūlou, ua hāʻule ka hoʻolālā ʻōpala. Hoʻohana mākou i nā hoʻokomo huʻa maʻamau me nā ʻoki no kēlā me kēia lālani poloka terminal, a ua hala mākou i kēlā me kēia hoʻāʻo hāʻule i nā makahiki ʻekolu i hala. Nānā pū nā hui kūʻai no ka ʻōpala palekana ESD (resistivity ʻili

ʻO ka lepili ʻana kekahi kiko loiloi: pono i kēlā me kēia pahu ke loaʻa kahi lepili me ka helu ʻāpana, ka nui, ke code lā, a me ka helu lot. Pono nā barcode e kūlike me GS1-128 no nā ʻōnaehana hale kūʻai automated. Ua ʻike mākou i nā mea loiloi e hōʻole ana i kahi ukana no ka mea ua haumia ka barcode a ʻaʻole hiki ke scan ʻia. He kikoʻī liʻiliʻi ia, akā he mea nui ia i nā logistics nui.

6. Palapala Hohonu Luʻu: Ka Hiki ke Hahai ʻia mai ka Resin a i ka Hoʻouna ʻana

Makemake nā hui kūʻai e huli i kēlā me kēia poloka terminal i kāna pūʻulu mea maka. ʻO ia hoʻi, ua komo pū ka loiloi i kahi loiloi o ke kaulahao palapala holoʻokoʻa: ka palapala hōʻoia loiloi a ka mea hoʻolako resin (CoA), nā palena mīkini hoʻoheheʻe (mahana, kaomi, manawa pōʻaiapuni), nā moʻolelo mālama make stamping, nā log ʻauʻau plating, a me nā hōʻike nānā hope loa. Mālama mākou i kahi ʻōnaehana traceability kikohoʻe kahi e pili ai kēlā me kēia helu lot i kēia mau moʻolelo āpau. Koho maʻamau nā mea loiloi i kahi helu lot a noi iā mākou e huki i nā palapala i loko o 15 mau minuke. ʻAʻole mākou i hāʻule i kēia hoʻāʻo.

ʻO kahi mea i ʻike ʻia maʻamau i ka loiloi ʻana, ʻo ia ka nalowale ʻana o nā moʻolelo calibration no nā kī torque i hoʻohana ʻia e hoʻonohonoho i ka ikaika paʻa o ka wili. Inā ʻaʻole i calibrated ʻia ka kī torque i loko o nā mahina 12 i hala, he mea kānalua ka holo hana holoʻokoʻa. Hoʻoponopono mākou i kēlā me kēia kī torque i kēlā me kēia 6 mahina a mālama i nā palapala hōʻoia ma ka faila. Pēlā nō, pono i ka CMM i hoʻohana ʻia no ka nānā ʻana i nā dimensional kahi palapala hōʻoia calibration o kēia manawa e hiki ke hahai ʻia iā NIST a i ʻole like. Hāʻawi mākou i nā kope i ka wā o ka loiloi.

Nānā pū nā hui kūʻai i kā mākou mau hōʻike kūlike ʻole (NCR) no ka makahiki i hala. Makemake lākou e ʻike ua ʻike mākou i nā kumu kumu a hoʻokō i nā hana hoʻoponopono. No ka laʻana, ua loaʻa iā mākou kahi NCR i ka makahiki i hala kahi i neʻe ai ke anawaena o ka pine i 0.96mm ma muli o ke komo ʻana o ka make stamping. Ua hoʻopaʻa mākou i ke kumu kumu (ka hoʻokomo make i ʻaʻahu ʻia ma hope o 500,000 mau pōʻaiapuni), ka hana hoʻoponopono (hoʻololi i ka hoʻokomo a hoʻonui i ka pinepine o ka nānā ʻana i kēlā me kēia 10,000 mau pōʻaiapuni), a me ka hōʻoia (10,000 mau ʻāpana a pau i loko o nā kikoʻī). Kūkulu kēlā pae o nā kikoʻī i ka hilinaʻi. Nā kumuwaiwai waho e like me Nā ʻōnaehana hoʻokele maikaʻi ISO 9001:2015 e hoʻolako i ke kahua no kēia palapala.

7. Ka Hiki Hana Ma Ka Pūnaewele: Ka Hana Holomua ma ka Hale Hana

ʻO ke kaʻina hana loiloi hope loa he hele kino ʻana o ka papahele hana. Ke nānā nei nā hui kūʻai i ʻelima mau mea: ka maʻemaʻe, ka mālama ʻana i nā lako, ke aʻo ʻana i ka mea hoʻohana, ka hoʻonohonoho ʻana i ke kahe hana, a me ka palekana. ʻO kahi wahi hoʻoheheʻe inikini lepo me nā ninini ʻaila ma ka papahele he hae ʻulaʻula koke ia—hōʻike ia i ka kaohi hana maikaʻi ʻole. Mālama mākou i kahi ʻōnaehana 5S (Sort, Set in Order, Shine, Standardize, Sustain) a lawe pinepine nā loiloi i nā kiʻi e hoʻohālikelike me kā mākou mau kaʻina hana i palapala ʻia.

Nānā ʻia nā moʻolelo mālama lako: aia nā mīkini hoʻoheheʻe ma kahi papa hana mālama pale? Nānā ʻia nā make stamping ma hope o kēlā me kēia 100,000 mau pōʻaiapuni? Hōʻike mākou iā lākou i kā mākou mau moʻolelo mālama, e komo pū ana me nā nānā lubrication i kēlā me kēia lā a me nā ana ʻaʻahu make hebedoma. Nānā pū ʻia nā moʻolelo hoʻomaʻamaʻa mea hoʻohana—pono kēlā me kēia mea hoʻohana i kahi palapala hōʻoia o kēia manawa no kā lākou ʻano mīkini. Hāʻawi mākou i ke aʻo makahiki a mālama i kahi matrix mākaukau.

He mea nui ka hoʻonohonoho ʻana i ke kaʻina hana: pono e lepili maopopo ʻia nā mea maka a hoʻokaʻawale ʻia mai nā mea i hoʻopau ʻia. Hoʻohana mākou i nā ʻōpala i hoʻopaʻa ʻia i ke kala: ʻōmaʻomaʻo no ka nānā ʻia a ʻae ʻia, melemele no ka quarantine, ʻulaʻula no ka hōʻole ʻana. Hōʻoia nā loiloi ua laka ʻia ka wahi quarantine a ʻo nā limahana i ʻae ʻia wale nō ke komo. ʻAʻole hiki ke kūkākūkā ʻia ka palekana: nā kū ulia pōpilikia ma nā mīkini āpau, nā mea kinai ahi me nā lepili nānā mahina, a me ka mālama ʻana i nā PPE. Ua hala mākou i kēlā me kēia loiloi palekana no ka mea ke mālama nei mākou iā ia ma ke ʻano he waiwai koʻikoʻi, ʻaʻole he pahu hōʻoia.

Ua hoʻolilo kekahi hui kūʻai mai kahi ʻoihana automation ʻEulopa i hoʻokahi lā holoʻokoʻa ma kā mākou papahele, e helu ana i kēlā me kēia ʻanuʻu hana a hoʻohālikelike iā ia me kā mākou mau manawa pōʻaiapuni i palapala ʻia. Ua ʻike lākou ʻo ko mākou manawa pōʻaiapuni maoli no ke kālai ʻana i ka hale 301-5.0 he 28 kekona, e hoʻohālikelike ʻia me 30 kekona i palapala ʻia. ʻO kēlā palena 2 kekona i hāʻawi iā lākou i ka hilinaʻi i ko mākou hiki ke hoʻokō i kā lākou kauoha 100,000-unit i loko o 4 mau pule. ʻAʻole wale ka hele wāwae e pili ana i ka loaʻa ʻana o nā pilikia - e pili ana i ka hōʻoia ʻana e hiki i ka mea hoʻolako ke hoʻokō i nā ʻōlelo hoʻohiki.

Nā nīnau i nīnau pinepine ʻia: Nā nīnau loiloi kauoha nui o ka poloka terminal
