Ulwaleko 4 ENIG isiqingatha umngxuma PCB 12026

I-PCB yesiqingatha semingxuma emva kokuba yenze udonga lobhedu emnyama, intsalela ye-burr, ukuphambuka kube yingxaki enzima kwinkqubo yokubumba yefektri ye-PCB. Ngokukodwa wonke umqolo weemingxunya ezinesiqingatha ofana nemingxunya yesitampu, umgodi umalunga ne-0.6 mm, isithuba sodonga lomngxunya si-0.45 mm, isithuba somfanekiso ongaphandle yi-2 mm, kuba isithuba sincinci kakhulu, kulula ukwenza isekethe emfutshane kuba yesikhumba sobhedu.

Iindlela zokwenza i-PCB yesiqingatha semingxunya sisinyithi zii-CNC zokugaya umatshini, ukubetha umatshini wokubetha, ukusika i-V-CUT njalo njalo, ezi ndlela zokucoca ekususeni isidingo senxalenye yomngxunya yokwenza ubhedu, ayinakukhokelela Inxalenye eseleyo yecandelo lomngxunya we-PTH yocingo lobhedu olushiyekileyo, i-burr, udonga olunzulu lomngxunya wesikhumba sobhedu, into exobukayo. kwelinye icala, xa kusenziwa umngxunya wesinyithi osisinyithi, ngenxa yempembelelo yokwandiswa kwe-PCB kunye nokuncipha, indawo yokuchaneka ngokuchanekileyo kunye nokwenza ukuchaneka, ubungakanani bokuphambuka kwesiqingatha somngxuma oshiyekileyo kwicala lasekhohlo nasekunene leyunithi inkulu , Ezisa ingxaki enkulu kwindibano ye-welding.
