[Martin] anatumiza funsoli pamzere wokumbutsa pamodzi ndi chithunzi chachikulu, ndipo anafotokoza mfundo yabwino. Ma board ambiri opanga ndi owunikira ali ndi mizere ingapo ya ma pin, omwe nthawi zambiri amakhala omasuka mu phukusi - soldering imasiyidwa kwa wogwiritsa ntchito. Kuti tikhale osamala, nthawi zambiri timapanga ma board a prototype okhala ndi mitu yambiri yochotsera zolakwika ndi kuyesa. Koma monga momwe [Martin] anatikumbutsira, pali njira zina zosinthira m'malo mwa kuwotcherera.
Ngati mukufuna kuyika bolodi la circuit mu khadi lina (mwachitsanzo, kuyika kapu mu Raspberry Pi), njira izi sizingathandize. Komabe, mukangofuna kupeza zizindikiro za serial port kapena kuzindikira zizindikiro zina za digito za I/O, kuyika zina mwa izi mu bokosi la zida kungakupulumutseni nthawi ndi mavuto a soldering joints. Kodi muli ndi njira zilizonse zopangitsa kuti soldering headers zikhale zosavuta, kapena kuzipewa konse? Chonde tidziwitseni mu ndemanga pansipa.
Sindikuganiza kuti ndili ndi zingwe za pin header ndipo nthawi zonse ndimasungunula mawayawo mwachindunji m'mabowo omwe ma pin header ayenera kupita.
Ndikukumbukira ndikugwira ntchito pa bolodi lamagetsi lokhala ndi cholumikizira cha crimp backplane kalekale (komanso chodalirika kwambiri), kotero ndinafufuza mwachangu mbewa, mutha kupezanso zolumikizira za crimp, mwachitsanzo Amphenol BPH7B10H00LF ndi 10-way rows 2 rows 0.1 inch pitch.
Ngati wina ali ndi njira yatsopano yotsika mtengo yolumikizira ma IO onse ofunikira ndi ma signals pa bolodi lowunikira...ndikuvomereza. Koma tsopano, kwa ma microcontroller, cholumikizira cha 0.1-inch ndicho chabwino kwambiri kwa wopanga ma tinker. Zachidziwikire, ngati simugwiritsa ntchito kwambiri zida zamagetsi (monga ma wifi kapena ma Ethernet board), simukusowa zambiri. Mwina ndi cholumikizira chokhazikika kapena basi ya I2C, ndi zina zotero?
Inde, ndicho chimene ndikuganiza...Ndimakonda mitu ya mainchesi 0.1. Yosavuta kwambiri kusokedwa, yosavuta kuyika ma lead oyesera a ic clip. Yaikulu mokwanira kuti mutha kuwona zomwe mukuchita, nthawi zambiri mutha kugwiritsa ntchito Sharp kapena nail polish kuti mulembe ma pini osangalatsa pa bolodi kapena pansi pa pulasitiki. Mutha kuwayika pa bolodi. Ingogwiritsani ntchito ukadaulo wosavuta kwambiri pazolinga zanga.
Chifukwa chokha chomwe ndimadumpha mutuwu ndichakuti ngati ndikufunika kuuyika m'bokosi laling'ono kumapeto, pamenepa, ndili ndi mwayi (ymmv) kugwiritsa ntchito ic clip lead mwachindunji pa dzenje la pcb. Koma kwenikweni, ndikapanga prototyping, nthawi zambiri sindimasamala kwambiri za kukula, ndipo ngati nditagwiritsa ntchito prototype electronics m'bokosi lomaliza, sindidzadula mzere woyesera kuti ndisunge malo.
Zifukwa: mtengo, malo. 1) Pazinthu zamalonda, mtengo wa zolumikizira ndi kuziyika umawonjezeka. Izi zimapangitsa kuti malonda anu asakondedwe poyerekeza ndi zinthu zomwe zimatsika ndi masenti 10. 2) Ndapanga mapangidwe ambiri, ndipo cholumikizira cha mainchesi 0.1 chochotsera zolakwika/kukonza mapulogalamu chimatenga malo ambiri (voliyumu) kuposa gawo lonselo!
Ngakhale izi zingakhale zoona, pali maluso oyambira okhudzana ndi zosangalatsa... Zamagetsi *nthawi zonse* ndi zosangalatsa, ngakhale ntchito yomwe imafuna luso linalake, ndipo kugwiritsa ntchito solder ku ma circuits ndikosavuta. Kutha kupanga maulumikizidwe kwakhala patsogolo nthawi zonse.
Tsopano *kale* pali zinthu monga ma adapter olumikizira ma winding ndi screw kuti achepetse kapena athetse kufunikira kwa soldering, koma izi zimawononga malo, ndipo nthawi zina zimakhala zofunikirabe soldering kapena kulipira ndalama zambiri posankha ma terminal a screw. Ngati izi zikukuvutitsani, pepani, koma izi ndi zoona, ndipo "mawonedwe osiyanasiyana" nthawi zambiri sangatheke ngati simukuwaganizira mwanjira zina. Mwina lingaliro "lofunika" kwambiri ndi kuzindikira kuti anthu ena sangakwanitse kuchita zinthu zina popanda luso linalake.
Ndikuganiza kuti sindikumvetsa momwe zimakhalira zopweteka kwambiri kusungunula ma pin headers. Nditha kumaliza mzere wa ma pin 40 bwino mumphindi imodzi yokha. Mwina ndichifukwa choti ndimachita izi pafupipafupi? Ndikuwona kuti izi ndizothandiza pazinthu zomwe nthawi zambiri zimakhala m'malo obisika osavuta kugwiritsa ntchito.
Nthawi zina kuyesa ndi kupanga ma prototyping popanda solder ndi lingaliro labwino komanso losinthasintha. Ndangoyitanitsa mitundu yambiri ya zovala pa AliExpress. Ndipo mukudziwa kuti ngati mugwiritsa ntchito mutu womaliza, bolodi limenelo lidzaphulika.
Iyi ndi njira yomwe ndimakonda kwambiri yosokera cholumikizira cha ma pin 40 (mfundo yowonjezera ya "sponge must die" sequence yomaliza). https://www.youtube.com/watch?v=i9pd9sY0Tjg
Njira ya mnzanu Ralph yochitira zinthu ndi yofala kwambiri. Monga ena adanenera, mitu ya 0.1-inch ndi yovuta kuigonjetsa. 2mm (pakadali pano) ndi yoyipa...
Bolodi loboola lidzasunga mapini ali bwino komanso pamalo ake panthawi yosokera. Makamaka ngati mugwiritsa ntchito mitu yambiri motsatizana.
Ndikadasokera mutu wa mwamuna, ndikanauphatikiza ndi mutu wa mkazi panthawi yosokera kuti mapini azikhala owongoka akatenthedwa.
Ichi ndi chizolowezi chabwino pafupifupi pa mtundu uliwonse wa cholumikizira. Ndimagwiritsa ntchito chilichonse kuyambira ma header mpaka ma XT90 power connectors akuluakulu. Palibe choipa kuposa kutaya zolumikizira zomwe zasungunuka pang'ono kwa moyo wonse wa chipangizocho.
Ndimakonda kwambiri mawonekedwe a TagConnect, koma nthawi zonse ndimaona kuti mtengo wake ndi wokwera pang'ono, kotero ndidapanga kapangidwe kameneka pamtengo wochepa: https://hackaday.io/project/171391-tagless-programmer
> […] Ma pin clip otsika mtengo a pogo. Mutha kugula zinthuzi kuchokera kwa ogulitsa zida zamagetsi aku Asia omwe mumakonda pamtengo wotsika kuposa $10.
Zoonadi, ali ngati madola 35. Ndikumvetsa, si madola 10, koma ndi chida chogwiritsidwanso ntchito. Kuphatikiza apo, OG idzakhala yodalirika komanso yothandizidwa. Adzakupatsani chizindikiro chomwe adachiwona bwino.

Ma pin a pogo otsika mtengo amadulidwa pachithunzi choyamba ndipo amagwiritsa ntchito mtunda wa pin wa 0.1" wa cholumikizira cholunjika. Sagwiritsa ntchito malo apadera kapena amafunikira chithandizo. Ngati mulibe malo olumikizira a 0.1", TagConnect ingakhale yothandiza.
Zikuoneka kuti pali mapangidwe ochepa kwambiri a momwe mungalumikizire ku ma header pads, koma ngati tikuganiza kuti sitinasonkhanitse ma header, koma nthawi zonse timagwiritsa ntchito ma pogo pini, ndi zina zotero, kodi kapangidwe kabwino ka "connector pads" ndi kotani? Mwina ndi mawonekedwe a mano, omwe amalolabe module kuti isonkhanitsidwe ku carrier board, ndi zina zotero?
Chodabwitsa n'chakuti, anthu ena amatsutsa kugwiritsa ntchito izi pazifukwa zina zopanda nzeru, kuphatikizapo khama lonse "lowonjezera" loyika bolodi la circuit pogwiritsa ntchito kapangidwe kameneka (sankhani phazi limodzi m'malo mwa lina), zomwe zimandipangitsa kumva ngati zachilendo. Membala wa forum wotchuka adatsutsa za kupusa kwake kwa makoswe awa, ndipo adaletsedwa kwa mwezi umodzi. Mtima wake udalitseni.
Inde, ndimatha kusoka zolumikizira za mainchesi 0.1, koma n'zosavuta kugwiritsa ntchito maloko opondapo mapazi. Ndikukumbukira bwana wanga akulimbikitsa kuti tigwire ntchito mwanzeru m'malo molimbikira.
Ili ndi lingaliro labwino, ndipo ma pin angakhudze ma pin onsewa - kotero mutha kuyika cholumikizira mwachangu mu pulogalamu kapena kukonza zolakwika kenako ndikuchichotsa popanda kusoka.
Ndangogula kumene zida za PCBite zoyesera malo oyesera ngati njira ina m'malo mwa soldering flying leads ku bolodi lililonse la circuit. Ndi seti ya ma pogo pini pa gooseneck. Sizotsika mtengo, ndipo zogwirira za probe ndi zazikulu kwambiri, zomwe zimapangitsa kuti zikhale zovuta kuzindikira zizindikiro zomwe zili pafupi, koma apo ayi ndizothandiza kwambiri. Zimawonekanso zokongola kwambiri!
Pa pulojekiti yokhala ndi ma board ambiri oyeserera, ndakhutira kwambiri ndi http://protofusion.org/wordpress/2013/05/open-hardware-pogo-pin-programmer/. Komabe, ngati mutayika bolodi la pogo molakwika, mudzabwerera ku mfundo yoyambirira.
Ndakhala ndikugwiritsa ntchito Tag-Connect pa ma board anga onse kwa zaka zambiri, mosatengera kapangidwe kake. Ndi mtengo wake.
Njira ina 1. Ma Pogopin, otsika mtengo kwambiri. Ndipo, ngati mukufuna kupanga choyesera cha bolodi lanu la circuit, chonde koperani kapangidwe ka bolodi la circuit ndikuwonjezera dzenje la 1mm kulikonse komwe mukufuna kuyesa malo, kenako ikani ma pogo pini pamabowo awa ndikulumikiza njanjiyo ku Connector yoyenera.
Njira ina yothandiza kwambiri 2: Ngati muli ndi mapini ochepa, mpaka mapini anayi motsatizana, kapena 2×3, bowolani mabowo a zolumikizira za 2 mm. Mutu wamba wa 0.1 inchi wamwamuna udzagwirizana bwino ndi dzenjelo, chifukwa cha pini yokhota pang'ono kuti isunge bwino.
Mwina mungayese cholumikizira cha Pogo cha mizere iwiri. Kondani izi. https://www.pogo-pins.com/products/629.html Ndikukhulupirira kukuthandizani. Andy
Pogwiritsa ntchito tsamba lathu ndi mautumiki athu, mukuvomereza momveka bwino kuti ma cookie athu agwire ntchito, magwiridwe antchito, ndi malonda aziikidwa. Dziwani zambiri
