Izinhlangothi zangaphambili nezingemuva zesifunda se-PCB ngokuyisisekelo izingqimba zethusi. Ekwenziweni kwemibuthano ye-PCB, noma ngabe ungqimba lwethusi kukhethwe amanani wezindleko eziguqukayo noma ukungezwa okunamadijithi amabili nokususa, umphumela wokugcina uyindawo enhle yokugcina. Yize izakhiwo ezibonakalayo zethusi zingathokozi njenge-aluminium, i-iron, i-magnesium, njll. Uma kucatshangelwa ukuba khona kwe-CO2 ne-Water Vapor emoyeni, ingaphezulu kwabo bonke ithusi ngemuva kokuxhumana negesi, ukusabela kabusha kwe-redox kuzokwenzeka ngokushesha. Uma kucatshangelwa ukuthi ubukhulu be-Copper ungqimba kumjikelezo we-PCB mncane kakhulu, ithusi ngemuva kokuthi i-air oxidation izoba yisimo sikagesi esiqinile, esizolimaza kakhulu izici ze-PCB.

Ukuze uvikele kangcono i-oxidation yethusi, futhi uhlukanise kangcono izingxenye ze-welding kanye ne-welding welding we-PCB ngesikhathi sokufudumala kagesi, futhi ukuze ulondoloze kangcono ubuso be-PCB, onjiniyela bezobunjiniyela badale izembatho ezihlukile zokwakha. Izambatho zokwakha ezinjalo zingavinjelwa kalula ebusweni be-PCB Circuit, okuholele ekutheni kube yisigqila songqimba oluvikelayo okufanele lube mncane futhi luvimbele oxhumana naye wethusi kanye negesi. Le nhlangano ibizwa ngokuthi ithusi, futhi impahla eluhlaza esetshenzisiwe imaskhi ye-solder
