Judge the quality of PCB board by PCB color

First, PCB, as printed circuit board, mainly provides interconnections between electronic components. Kaore te tae e pa ana ki te mahinga, a, ko te rereketanga o nga tae e kore e pa ki nga mahi hiko. Ko te mahinga PCB e whakatauhia ana e nga rauemi e whakamahia ana (Q nui), hoahoa waea waea, me te maha o nga papa. However, in the process of PCB washing, black is the most likely to cause color difference. If the raw materials and production process used by PCB factory are slightly different, PCB defect rate will increase due to color difference. Ma tenei ka tika te piki ake o nga utu whakaputa.

Inaa hoki, ko nga rauemi mata a PCB kei nga waahi katoa o ta taatau ao, ko te muka karaihe me te kara tera. Fiberglass combines with resin and hardens into a board that is insulated, insulated and not easily bent. This is a PCB substrate. Ae ra, ko te taapiri PCB i hangaia i te muka karaihe me te karauna anake kaore e taea te whakahaere i te tohu, na runga i te tihi PCB, ka taupokina e te kaiwhakanao te papa me te parahi parahi, no reira ka kiia hoki ko te tihi PCB ka taea te karanga ko te korowai-pania-parahi.

Na te mea he uaua ki te tautuhi te ara iahiko o te PCB pango, ka piki ake te uaua ki te tiaki me te whakakore i te waahanga o muri me te hokonga. Ko te tikanga, mena kaore he parani me nga kaihoahoa RD (RESEARCH me te whanaketanga) me te roopu tiaki kaha me nga pukenga hohonu, kaore e maamaa te whakamahi i te PCB mangu. Ka taea te kii ko te whakamahinga o te pango PCB te whakaatu i te maia o te parani ki te hoahoa RD me te roopu tiaki mutunga. Mai i te taha, he tohu ano mo te maia o te kaihanga ki o raatau ake pakaritanga.

I runga i nga take o runga ake nei, ka ata whakaarohia e nga kaihanga nui te tohu i te hoahoa putanga PCB mo a raatau hua. Therefore, most of the products with large market shipments in that year used red PCB, green PCB or blue PCB version. Black PCB can only be seen on middle and high-end or top flagship products, so don’t think that black PCB is better than green PCB any more.
