Papan sirkuit PCBmetode perawatan permukaan
Lima pangolahan perawatan lumahing umum Ana akeh pangolahan perawatan lumahing kanggo produksi PCB. Sing umum yaiku leveling udara panas, lapisan organik, nikel / emas immersion tanpa elektro, perak immersion lan timah immersion.









Proses pencelupan timah bisa mbentuk senyawa intermetalik tembaga-timah sing rata. Fitur iki ndadekake timah kecemplung duwe solderability apik padha karo leveling udhara panas tanpa masalah flatness sirah saka leveling udhara panas; ora ana electroless nikel plating kanggo kecemplung timah / Difusi antarane kecemplung logam emas-tembaga-timah senyawa intermetallic bisa kuwat kaiket bebarengan. Piring timah kecemplung ora bisa disimpen suwe banget, lan perakitan kudu ditindakake miturut urutan timah kecemplung.
