IPCB inkqubo edgeLumphetho webhodi omde ongenanto osetelwe indawo yothumelo lwengoma kunye nokubekwa kweendawo zokubeka amanqaku ngexesha lokusetyenzwa kwe-SMT. Ububanzi bomphetho wenkqubo ngokubanzi malunga ne-5-8mm.

Kwinkqubo yoyilo lwe-PCB, ngenxa yezizathu ezithile, umgama phakathi komphetho wecandelo kunye necala elide le-PCB lingaphantsi kwe-5mm. Ukuze kuqinisekiswe ukusebenza kakuhle kunye nomgangatho wenkqubo yendibano yePCB, umyili kufuneka afake umphetho wenkqubo kwicala elide elihambelana nePCB.

Iingqwalasela zenkqubo yePCB:

1. I-SMD okanye izixhobo ezifakwe kumatshini azikwazi ukulungiswa kwicala lobugcisa, kwaye amacandelo e-SMD okanye amacandelo afakwe kumatshini awakwazi ukungena kwicala lobugcisa kunye nendawo yalo ephezulu.

2. Iqumrhu lamacandelo afakwe ngesandla alikwazi ukuwela kwisithuba esingaphakathi kwe-3mm ukuphakama ngaphezu kweengqungquthela zenkqubo ephezulu nangaphantsi, kwaye ayikwazi ukuwela kwisithuba ngaphakathi kwe-2mm ubude ngaphezu kwemida yenkqubo ekhohlo nasekunene.

3. I-foil ye-copper conductive kwi-edge yenkqubo kufuneka ibe banzi kangangoko kunokwenzeka. Imigca engaphantsi kwe-0.4mm idinga ukuqiniswa kwe-insulation kunye ne-abrasion-resistant treatment, kunye nomgca weyona ndlela iphezulu ayikho ngaphantsi kwe-0.8mm.

4. Umphetho wenkqubo kunye nePCB inokudityaniswa kunye nemingxuma yesitampu okanye i-V-shaped grooves. Ngokuqhelekileyo, i-grooves ene-V isetyenziswa.

5. Akufuneki kubekho iipads kunye nemingxuma ekupheleni kwenkqubo.

6. Ibhodi enye enendawo enkulu kuno 80 mm² ifuna ukuba iPCB ngokwayo ibe neperi yenkqubo ehambelanayo, kwaye akukho zixhobo zingena kwizithuba eziphezulu nezisezantsi kumphetho wenkqubo.

7. Ububanzi bomda wenkqubo bunokwandiswa ngokufanelekileyo ngokwemeko yangempela.
