Le khasiI-PCB inqubo enqenqemeniIngabe umngcele webhodi ongenalutho ongenalutho olungiselelwe isikhundla sokudluliswa kwethrekhi nokubekwa kwamaphoyinti amamaki okubekisa ngesikhathi sokucutshungulwa kwe-SMT. Ububanzi bamaphetheli wenqubo ngokuvamile buyi-5-8mm.

Enqubweni yokuqamba kwe-PCB, ngenxa yezizathu ezithile, ibanga phakathi konqenqema lwengxenye nohlangothi olude lwe-PCB lungaphansi kwe-5mm. Ukuze uqinisekise ukusebenza kahle kanye nekhwalithi yenqubo yomhlangano we-PCB, umklami kufanele wengeze umngcele wenqubo ohlangothini olude lwe-PCB

Ukucatshangelwa kwenqubo ye-PCB Enqenqemeni:

1. Izakhi ezifakiwe ze-SMD noma ezifakiwe

2. Ibhizinisi lezinto ezifakiwe ezenziwa ngesandla alikwazi ukuwela esikhaleni ngaphakathi kokuphakama kwe-3mm ngaphezulu kwemiphetho yenqubo engenhla nangaphansi, futhi ayikwazi ukuwela esikhaleni ngaphakathi kwamaphethelo we-2mm ngaphezulu kwemiphetho yenqubo yesobunxele nangakwesokudla.

3. I-foil ye-popper esebenzayo emaphethelweni enqubo kufanele ibe kabanzi ngangokunokwenzeka. Imigqa engaphansi kuka-0.4mm idinga ukufakwa okuqinisiwe kanye nokwelashwa okuvinjezelwe i-abrasion, kanye nolayini onqenqemeni kakhulu alukho ngaphansi kuka-0.8mm.

I-4. Unqenqema lwenqubo kanye ne-PCB lungaxhunywa ngezimbobo zesitembu noma ama-v-shaped grooves. Ngokuvamile, kusetshenziswa ama-grooves abunjiwe ama-V.

5. Akufanele kube namaphakethe nangezimbobo onqenqemeni lwenqubo.

7. Ububanzi bonqenqemeni lwenqubo bungakhuphuka ngokufanele ngokwesimo sangempela.
