Kodi zinthu zomaliza za PCB zitha kusungidwa nthawi yayitali bwanji?

Msonkhano wa PCBndi bolodi kuti solders zosiyanasiyana zigawo padziko kusindikizidwa dera bolodi.Ndi chitukuko cha sayansi ndi luso, anthu ayamba kulabadira kwambiri ntchito nthawi ya PCB msonkhano dera bolodi ndi kudalirika kwa ntchito mkulu-pafupipafupi, ndiyeno PCB msonkhano nawonso kwambiri ndi tcheru kwambiri alumali moyo.Nthawi yabwinobwino, nthawi yosungiramo msonkhano wa PCB ndi zaka 2 ~ 10.

Ma board omaliza a PCB omwe amakhudza magawo osungira:

1. Zinthu zachilengedwe

Malo achinyezi ndi fumbi mwachiwonekere sangagwirizane ndi kusungirako msonkhano wa PCB.Zinthu izi zimathandizira kutulutsa ndi kuyipitsa kwa PCB ndikufupikitsa moyo wa alumali.Nthawi zambiri, tikulimbikitsidwa kusunga gulu la PCB pamalo owuma, opanda fumbi ndi kutentha kosalekeza kwa 25°C.

2. Kudalirika kwa zigawo

Kudalirika kwa zigawo pa PCBAs osiyana komanso chimatsimikizira alumali moyo wa PCB msonkhano pamlingo waukulu.Zida zomwe zimagwiritsa ntchito zida zapamwamba komanso njira zimatha kukana madera ovuta.Ili ndi kuthekera kokulirapo komanso kukana kwa okosijeni kolimba.Zimaperekanso chitsimikizo cha kukhazikika kwa msonkhano wa PCB.

3. Ukadaulo waukadaulo wapa PCB wazinthu ndi pamwamba

bolodi losindikizidwazipangizo sizimakhudzidwa mosavuta ndi chilengedwe, koma njira yawo yothandizira pamwamba imakhudzidwa kwambiri ndi okosijeni wa mpweya.Chithandizo chabwino chapamwamba chimatha kutalikitsa moyo wa alumali wa msonkhano wa PCB.

4. PCBA bolodi kuthamanga katundu

Kuchulukirachulukira kwa msonkhano wa PCB ndiye chinthu chofunikira kwambiri pashelufu yake.Mkulu pafupipafupi ndi mkulu katundu ntchito adzabala mosalekeza mkulu zotsatira pa mizere ndi zigawo zikuluzikulu za bolodi dera, amene mosavuta oxidize mchikakamizo cha Kutentha, chifukwa dera lalifupi ndi lotseguka dera pa ntchito yaitali.Choncho, magawo ntchito ya bolodi PCB msonkhano ayenera kukhala mkati osiyanasiyana a zigawo zikuluzikulu kupewa kuyandikira mtengo pachimake, kuti bwino kuteteza PCB msonkhano ndi kutalikitsa moyo wake yosungirako.

Tili ndi chidaliro kukupatsirani kuphatikiza kwabwino kwambirikutembenukira kiyi PCB msonkhano msonkhano, khalidwe, mtengo ndi nthawi yobweretsera mu dongosolo lanu la Small batch voliyumu ya PCB ndi Mid batch Volume PCB dongosolo la msonkhano.

Ngati mukuyang'ana wopanga msonkhano wabwino wa PCB, chonde tumizani mafayilo anu a BOM ndi mafayilo a PCB sales@pcbfuture.com.Mafayilo anu onse ndi achinsinsi kwambiri.Tikutumizirani mawu olondola okhala ndi nthawi yotsogolera mu maola 48.
