10 Layer ENIG FR4 Tg150 PCB

ʻO ka pōmaikaʻi nui o nā mea Tg kiʻekiʻe ʻoi aku ka kiʻekiʻe o ka wela hana (MOT), hiki ke lawe i kēia manawa.Wahi a ka ʻike, hiki ke hoʻohana ʻia ʻo TG ma kahi o 20 ℃ e like me ka mot.Ma kēia mahana, hiki i ka PCB ke holo maʻamau no ka manawa lōʻihi me ka ʻole o ka pōʻino.

ʻOi aku ka haʻahaʻa o ka mahana pale wela o ka mask solder maʻamau ma mua o ka Tg o ka substrate.ʻO ka mahana hana maʻamau o ka solder mask ma kahi o 150 ℃.No nā noi Tg kiʻekiʻe ma mua o kēia mahana, makemake ʻia e koho i ka PCB me ka ʻole o kahi huna huna a i ʻole ke kau ʻana i ka uhi pale wela kiʻekiʻe ma hope o ka hui ʻana.Inā hoʻohana ʻia ka mask solder maʻamau i ke kaiapuni kiʻekiʻe, e lilo ka mask solder i ʻeleʻele hina.
