12 Txheej ENIG FR4 Dig muag Vias PCB

HDI PCB cov ntaub ntawv yog RCC, LDPE, FR4

RCC:Resin coated tooj liab yog luv luv rau resin coated tooj liab ntawv ci.RCC yog tsim los ntawm cov ntawv ci tooj liab thiab cov resin nrog ntxhib saum npoo, tiv thaiv tshav kub thiab tiv thaiv oxidation kev kho mob (siv thaum lub thickness yog ntau tshaj 4mil). Cov txheej txheej ntawm RCC muaj cov txheej txheem tib yam li FR4 daim ntawv nplaum (prepreg).Tsis tas li ntawd, nws yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua ntawm cov laminate, xws li:

(1) High rwb thaiv tsev kev ntseeg tau thiab micro ntawm kev ntseeg tau;

(2) Kev hloov pauv ntawm iav siab (TG);

(3) Tsawg dielectric tsis tu ncua thiab dej nqus;

(4) Nws muaj adhesion siab thiab lub zog rau tooj liab ntawv ci;

(5) Tom qab kho, lub thickness ntawm rwb thaiv tsev txheej yog uniform
