Pulogalamu ya PCB mtengo, wopanga zamagetsi aliyense kapena wopanga amafuna kudziwa momwe angapezere mawu abwino pamsonkhano wa PCB ndi momwe mtengo umakhudzira mtengo wa PCB. Nawa maupangiri amomwe mungayang’anire mitengo yamisonkhano ya PCB.

Choyamba, mvetsetsa bwino zomwe mtengo wa PCB Assembly (PCBA) umachita. Zina mwa zoyendetsa zazikulu kwambiri ndizo:

(1) Mtundu wa Assembly Surface Mount (SMT) (SMD chigawo) Kupyola muenje (DIP) kusakaniza (zonse)

(2) Kukhazikitsidwa kwamagawo kumangopempha gawo lapamwamba kuti lipemphe msonkhano wa mbali ziwiri wa Doulbe

(3) Zigawo zonse (SMD + DIP)

(4) Kukula kwa phukusi lachigawo 1206 0804 0603 0402 020101005

(5) Kuphatikizira kophatikizira (choyambirira patsogolo) Reel lamba wa thireyi kapena kudula chikwama chomata chopanda lamba

(6) SMT SMT kudzera mu bowo lokhazikika kudzera mumabowo otsegulira mzere wozungulira wojambula (AOI); br> X – ray kusankha solder Buku solder msonkhano

(7) Kuchuluka ndi kukula kwa batch

“Sungani Panelize kusinthasintha kuti mukwaniritse zosowa za omwe akukupangitsani.”

Muyenera kuwonetsetsa kuti kukhathamiritsa kumapangidwira zosowa za opanga PCBA.

(8) Zofunikira pakukonzekera ziwalo zapadera (mwachitsanzo, kutalika kwa lead, kutalika / kutalika kwakutali, kutalikirana)

(9) Mtengo wathunthu wa Bill of Materials wathunthu (BOM)

(10) Chiwerengero cha zigawo zopanda bolodi (PCB) ndi zida zomwe agwiritsa ntchito

Kusintha zigawo za PCB kumawononga ndalama zambiri kuposa ma board okhwima a PCB

(11) zokutira (zamankhwala kapena zankhondo nthawi zambiri zimafuna zokutira zonse kapena zokutira) Utsi kapena zokutira bulashi Kuchuluka kwa zokutira

(12) Zofunikira zoumba (ngati zilipo)

(13) Zofunikira kutsatira pamalamulo a RoHS (opanda lead) Osati ROHS (leaded) IPC-A-610D Class I, CLASS II kapena Class III ITAR

(14) Zofunikira pakuyesa (RayMing angakonde kuyesa matabwa onse a PCBA asanawatumize, tikufuna kuti utiuze momwe tingayesere) Kuyesa kwamphamvu pamagetsi (ICT) Kuyendetsa njinga osayesa (kuyang’ana kokha)

(15) Zoyendera zofunikira muyezo wa ESD (kutulutsa kwamagetsi) matumba osakhala ofanana / zotengera zapadera

(16) Kutumiza (RayMing imapereka ntchito yosanja mozungulira ya PCB)

Kuwongolera koyenera, kufunsa mwachangu Kuthamangira mwachangu (ntchito ndi zinthu zakuthupi zakhudzidwa)

Izi nsonga 16 zidzakhudza mtengo wa msonkhano wa PCB, chifukwa chake mutha kusankha yabwino kwambiri kuti isunge mtengo, mukamagula magawo, mutha kupereka gwero lazinthu zingapo pachinthu chilichonse, ndikosavuta kuwongolera zina, osati kuchokera digikey, othandizira ena amakhalanso ndi chida chamtengo wapatali chothandizira, mwachangu kuti achepetse mtengo

Konzani njira yopezera zinthu zotsika mtengo pakati paukadaulo wopanga ndi madipatimenti ogulitsa. Izi ndizosavuta kuzichita kuposa kuchita. Kusagwirizana koyambirira pakati pakupanga kwamakina ndi kugula kungalepheretse izi.

Yankho limodzi ndikukhazikitsa makomiti ochepetsa mtengo. Management imagwira ntchito zogula ndi zomangamanga kuti izindikire mwayi wotsika mtengo kwambiri. Amagwiritsanso ntchito kuzindikira magawo omwe amafunikira magwero angapo kuti zitsimikizidwe ndikupangidwa mosalekeza.
