Kungaqwalaselwa ukuba zininzi imingxunya nezincinci kwiBhodi yeSiphaluka, kwaye inokufunyanwa ukuba kukho imingxunya emininzi, kwaye umngxunya ngamnye wenzelwe injongo yako. Le mingxunya inokuhlulwa ibe ye-PT

Imigaqo ye-PCB: ngomngxunya, umngxunya ongaboniyo, umngxunya ongcwatywe.

1. Ungahlula njani i-PTE ne-NPTH ngemingxunya?

Ingagwetywa ukuba kukho amanqaku aqaqambileyo elenziwe ngodonga lomngxunya. Umngxunya onamanqaku okufaka i-electroplaitha yi-PT, kwaye umngxunya ngaphandle kwamanqaku okugcina i-electropting yi-NPTH. Njengoko kubonisiwe kumfanekiso ongezantsi:

2. IUI-Sage ye-npth

Kufunyanwa ukuba i-aperture ye-NPTH idla ngokuba inkulu kune-PTT, kuba i-Npth isetyenziswa kakhulu njengesikutyeke, kwaye ezinye zisetyenziselwa ukufaka unxibelelwano ngaphandle komnxibelelanisi. Ukongeza, abanye baya kusetyenziswa njengoxwebhu lovavanyo kwicala leplate.

3. Ukusetyenziswa kwePTE, yintoni nge-vale?

Ngokubanzi, imingxunya ye-PT kwiBhodi yeSekethe isetyenziswa ngeendlela ezimbini. Inye isetyenziselwa ukuvelisa iinyawo ze-dip ye-dip. I-aperture yezi mingxunya kufuneka ibe nkulu kunokuba ibekwe kububanzi beenyawo ze-welding zamalungu, ukuze zifakwe kwimingxunya.

Enye i-PT enye encinci, idla ngokubizwa ngokuba yi-Ho (yoMculo), isetyenziselwa ukuqhagamshela ibhodi yesekethe (i-PCB) iya kutyunjelwa, kuba i-PCB ingabanjiswanga, ukuba i-PCB ingabanjiswa, yiyo loo nto ibizwa "Dlulisa ngomngxunya" ngesiTshayina. Ngeenxahamba kuba imingxunya ayibonakali ngokupheleleyo ngaphandle. Kuba injongo ye-hine kukuqhuba i-foil ye-foil ye-laare, ifuna i-elektroplating yokuziphatha, ngokunjalo ne-vale lunohlobo lwePTT.
