Yadda Ake Hana Rami Mara Tagulla a PCBs Mai Girma: Muhimman Bayani Kan Masana'antar PCB
Fahimtar Muhimmancin Girman Rami da Kauri a Masana'antar PCB
A cikin kera PCB, ana amfani da fasahar rabon girman rami da kauri, wanda kuma aka sani da rabon al'amari, muhimmin abu ne da ke tasiri ga ingancin rufin rami. Ana ƙididdige wannan rabo ta hanyar raba kauri na PCB da diamita na ramin, wanda galibi ake kira da diamita na ramin. Rabon tsayi-da-diamita (L/D).
Misali, idan kauri na PCB shine 1.60 mm kuma diamita na ramin shine 0.2 mm, rabon al'amari shine 8:1. Rabon al'amari na ƙasa yana nuna allon siriri tare da manyan ramuka, wanda yawanci yakan haifar da sakamako mafi kyau na plating saboda yawan rarraba ion daidai gwargwado yayin aikin electroplating.
