Rigid PCB nrog HASL

Zoo li OSP thiab ENIG, HASL yog cov txheej txheem kho saum npoo ntawm PCB. Xws li PCB pawg thawj coj tau siv dav hauv ntau yam khoom siv hluav taws xob, khoom siv sib txuas lus, khoos phis tawj, khoom siv kho mob, aerospace thiab lwm yam kev lag luam thiab cov khoom lag luam. Tin spraying, tseem hu ua cua kub solder leveling, yog abbreviated li HASL. Lub hauv paus ntsiab lus yog los tiv thaiv oxidation ntawm tooj liab nto ntawm lub rooj tsavxwm los ntawm txheej txheej ntawm tin txhuas alloy rau ntawm tooj liab. Ntxiv nrog rau kev tsim kev tiv thaiv ntawm qhov chaw ntawm lub substrate, lwm lub luag haujlwm tseem ceeb ntawm tin spraying phaj yog tswj kom muaj kev sib tw.

Kev faib tawm

Muaj cov hmoov txhuas HASL thiab tsis muaj HASL. Xav txog cov kev cai ib puag ncig, cov neeg siv khoom feem ntau xaiv cov hmoov txhuas tsis muaj hmoov txhuas.

Nta

1. Lub zog thiab kev ntseeg siab ntawm HASL phaj rau lub rooj tsav xwm Circuit Court yog qhov zoo, tab sis qhov flatness ntawm cov tin spraying kev kho mob tsis zoo.

2. Piv nrog rau lwm txoj kev kho saum npoo, HASL muaj cov nqi zoo tshaj plaws.

Lub sij hawm xa tuaj

# Hauv qab lub sijhawm txhuas yog raws li cov khoom me me thiab tom qab cov khoom siv raw tau npaj, Batch (ceev ceev) thiab Fast Run xav tau tus nqi ntxiv.
