Gusaba
Inzira zometseho kimwe cya kabiri ni:
1. Tunganya igice cyigice cyumwobo hamwe nigikoresho cyo gukata kabiri.
2. Imyitozo ya kabiri yongeramo umwobo uyobora kuruhande rwumwobo, ikuraho uruhu rwumuringa hakiri kare, igabanya burr, kandi ikoresha imashini ikata aho gukoresha imyitozo kugirango yongere umuvuduko no guta umuvuduko.
3. Shira umuringa kugirango uhindure amashanyarazi substrate, kugirango urwego rwumuringa rushyizwe mumashanyarazi kurukuta rwumwobo rwuruziga ruzengurutse ku kibaho.
4 ikibaho kirabyimbye kandi umuringa utwikiriwe nigitereko cyamabati kugirango irwanye ruswa;
5. Igice kimwe cya kabiri cyaciwe gabanya umwobo uzengurutse ku rubavu rw'ikibaho mo kabiri kugira ngo ugire umwobo;
6. Mu ntambwe yo gukuraho firime, firime irwanya amashanyarazi ikanda mugihe cyo gukanda firime ikurwaho;
7. Gufata substrate irashwanyagujwe, kandi umuringa ugaragara kumurongo winyuma wa substrate ukurwaho no gutera;
8. Amabati yambura substrate yambuwe amabati, kugirango amabati yo ku rukuta rwa kimwe cya kabiri ashobora gukurwaho, kandi umuringa uri ku rukuta rwa kimwe cya kabiri ugaragara.
9. Nyuma yo gukora, koresha kaseti itukura kugirango uhuze ikibaho cyibice, hanyuma ukureho burr unyuze kumurongo wa alkaline
10. Nyuma yumuringa wa kabiri wumuringa hamwe namabati yometse kuri substrate, umwobo uzengurutse kumpande yikibaho waciwemo kabiri kugirango ube umwobo wigice, kubera ko umuringa wumuringa wurukuta rwumwobo utwikiriye amabati, na umuringa wumuringa wurukuta rwumwobo ntaho uhuriye rwose nigice cyumuringa cyurwego rwinyuma rwa substrate Guhuza, birimo imbaraga zikomeye zo guhuza, birashobora kubuza neza urwego rwumuringa kurukuta rwumwobo gukururwa cyangwa kurigata umuringa mugihe ukata;
11. Nyuma yo gukora igice cya mwobo kirangiye, firime irakurwaho hanyuma igashyirwa hejuru, kugirango ubuso bwumuringa butazaba okiside, birinda neza ko habaho umuringa usigaye cyangwa n’umuzunguruko mugufi, kandi bikazamura umusaruro w’igice cya metani. -Ikibaho cyumuzunguruko wa PCB.
Ibibazo
Yashizwemo igice-cyobo cyangwa umwobo, ni impande ya kashe binyuze mu gukata kabiri kumurongo.Igice cya kabiri-umwobo ni urwego rwisumbuyeho rushyizweho impande zometse kumuzingo wacapwe, ubusanzwe ikoreshwa muburyo bwo guhuza.
Via ikoreshwa nkumuhuza hagati yumuringa kuri PCB mugihe PTH isanzwe ikorwa nini kuruta vias kandi ikoreshwa nkumwobo washyizweho kugirango wemererwe ibice - nkibirwanya bitari SMT, capacator, na DIP pack IC.PTH irashobora kandi gukoreshwa nkibyobo byo guhuza imashini mugihe vias idashobora.
Isahani ku mwobo ni umuringa, kiyobora, bityo ituma amashanyarazi agenda mu kibaho.Kudashyirwa mu mwobo ntibigira ubushobozi, niba rero ubikoresheje, urashobora kugira imirongo yumuringa yingirakamaro kuruhande rumwe rwibibaho.
Hano hari ubwoko 3 bwibyobo muri PCB, Bishyizwe Hanyuze Hobo (PTH), Bidashyizwe Kumurongo (NPTH) na Via Holes, ibi ntibigomba kwitiranywa na Slots cyangwa Cut-outs.
Uhereye kuri IPC isanzwe, ni +/- 0.08mm kuri pth, na +/- 0.05mm kuri npth.
