IPCB inqubo onqenqemeniiwunqenqema olude lwebhodi olungenalutho olusethelwe indawo yokudlulisela ithrekhi nokubekwa kwamaphoyinti omaka ngesikhathi sokucubungula i-SMT. Ububanzi bonqenqema lwenqubo ngokuvamile buba ngu-5-8mm.

Enqubweni yokuklama ye-PCB, ngenxa yezizathu ezithile, ibanga phakathi konqenqema lwengxenye kanye nohlangothi olude lwe-PCB lingaphansi kuka-5mm. Ukuze kuqinisekiswe ukusebenza kahle kanye nekhwalithi yenqubo yokuhlanganisa i-PCB, umklami kufanele engeze umphetho wenqubo ohlangothini olude oluhambisanayo lwe-PCB.

Ukucatshangelwa konqenqema lwenqubo ye-PCB:

1. I-SMD noma izingxenye ezifakwe umshini azikwazi ukuhlelwa ohlangothini lwezandla, futhi izinhlangano ze-SMD noma izingxenye ezifakwe umshini azikwazi ukungena ohlangothini lwezandla kanye nendawo yalo engaphezulu.

2. Ibhizinisi lezingxenye ezifakwe ngesandla alikwazi ukuwela esikhaleni esingaphakathi kuka-3mm ubude ngaphezu konqenqema lwenqubo olungenhla nangaphansi, futhi alikwazi ukuwela esikhaleni esingaphakathi kuka-2mm ubude ngaphezu konqenqema lwenqubo kwesokunxele nakwesokudla.

3. I-foil yethusi eqhutshwayo emaphethelweni enqubo kufanele ibe banzi ngangokunokwenzeka. Imigqa engaphansi kuka-0.4mm idinga ukufakwa okuqinisiwe kanye nokwelashwa okungazweli ukuhuzuka, futhi umugqa osemaphethelweni amaningi awukho ngaphansi kuka-0.8mm.

4. Unqenqema lwenqubo kanye ne-PCB kungaxhunywa nezimbobo zesitembu noma imifantu emise okwe-V. Ngokuvamile, kusetshenziswa ama-grooves amise okwe-V.

5. Akufanele kube namaphedi kanye nezimbobo emaphethelweni enqubo.

6. Ibhodi elilodwa elinendawo enkulu kuno-80 mm² lidinga ukuthi i-PCB ngokwayo ibe nepheya lemiphetho yenqubo ehambisanayo, futhi azikho izingxenye ezibonakalayo ezingena ezindaweni ezingaphezulu neziphansi zonqenqema lwenqubo.

7. Ububanzi bonqenqema lwenqubo bunganyuswa ngokufanelekile ngokuya ngesimo sangempela.
