[UVLED] PCB Circuit Board UVLED luam ntawv Lub teeb Source

PCB Circuit Board UVLED luam ntawv lub teeb qhov chaw yog LED nti ua lub PCB kho qhov muag kho tshuab nrog LED nti. Nws txawv ntawm PCB optical curing tshuab xws li mercury teeb thiab halogen teeb. Nws muaj zog heev, yog li tag nrho lub teeb lub zog ntawm UVLED luam ntawv lub teeb qhov chaw yog me me (piv rau tag nrho lub teeb lub zog ntawm lub teeb mercury) kom ruaj khov. PCB Circuit Board UVLED luam ntawv lub teeb lub hauv paus ntsiab lus: ntxiv lub teeb ua rau (lossis photoresist) rau cov resin ntawm cov mis tshwj xeeb, tom qab absorbing lub siab - siv ultraviolet lub teeb nyob rau hauv lub ultraviolet (UV) kho qhov muag khoom, lub active dawb radicals los yog ion puag yog generated, li no Kev kho ntawm aggregation, cross-linking, thiab branching tshua, cov resin (UV coatings, inks, adhesives, thiab lwm yam) hloov los ntawm cov kua rau cov khoom nyob rau hauv ib tug ob peb vib nas this (tsis muaj). PCB optical curing UVLED luam ntawv lub teeb ci tshuab PCB tus cwj pwm yam ntxwv: (1) viscosity: yog li -hu ua viscosity yog kev sib txhuam sab hauv ntawm cov kua, qhia tias nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam, ib txheej ntawm cov kua slides rau lwm txheej ntawm cov kua, thiab cov kua sab hauv yog siv rau cov kua dej sab hauv. Kev sib txhuam ntawm PCB luam ntawv number case yuav tsis raug khawb los ntawm cov khoom txawv teb chaws. (2) Tacticalness: Tentile yog cov yam ntxwv ntawm lub cev ntawm cov kua, uas yog, nws cov viscosity txo qis hauv lub xeev nplawm, thiab tom qab zoo li qub, nws yuav rov qab sai dua nws cov yam ntxwv viscosity. Los ntawm nplawm, cov nyhuv ntawm tactile degeneration txuas ntxiv mus ntev, uas yog txaus los ua kom nws cov qauv hauv kev sib raug zoo. Txhawm rau kom ua tiav cov txiaj ntsig zoo net luam ntawv, tactileness ntawm tus number case yog qhov tseem ceeb heev. (3) Fineness: Lub fillers ntawm pigments thiab minerals feem ntau yog khoom. Tom qab kev sib tsoo zoo, nws qhov loj me tsis pub tshaj 4/5 microns, thiab nyob rau hauv ib daim ntawv zoo los tsim ib homogeneous liquidity state. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tsum tau number case kom muaj fineness. Xav paub ntxiv yog txais tos nkag rau hauv
