Sida aynu wada ognahay, chip LED sida qaybta xudunta u ah nalka LED waa qalab semiconductor adag-state, wadnaha LED waa chip semiconductor ah, mid ka mid ah dhamaadka chip ku lifaaqan bracket ah, mid ka mid ah dhamaadka waa electrode negative ah, dhamaadka kale waxa uu ku xiran yahay electrode togan ee sahayda korantada, si ay chip oo dhan waxaa lagu duubay by resin epoxy. Marka sapphire loo isticmaalo sida walxaha substrate-ka, waxaa si ballaaran loo isticmaalaa soo saarista chips LED, iyo qalabka goynta dhaqameed mar dambe ma buuxin karo shuruudaha goynta. Haddaba sidee ku xalin kartaa dhibaatadan?
Mashiinka goynta laser-ka-gaaban ee picosecond waxaa loo isticmaali karaa in lagu jeexo wafers sapphire, kaas oo si wax ku ool ah u xalliya dhibka goynta sapphire iyo shuruudaha warshadaha LED-ka si loo sameeyo jajab yar iyo dariiqa goynta cidhiidhi ah, waxayna bixisaa suurtogalnimada iyo dammaanadda goynta hufan ee wax soo saarka ballaaran ee LED-ka ee ku salaysan sapphire.
Faa'iidooyinka goynta laysarka:
1, tayada goynta wanaagsan: sababtoo ah barta laser yar, cufnaanta tamarta sare, xawaaraha goynta, sidaas darteed goynta laser waxay heli kartaa tayada goynta wanaagsan.
2, wax ku oolnimada sare ee goynta: sababtoo ah sifooyinka gudbinta ee laser-ka, mashiinka goynta laysarka guud ahaan wuxuu ku qalabaysan yahay miisaska xakamaynta tirada badan, iyo habka goynta oo dhan wuxuu si buuxda u noqon karaa CNC. Markaad shaqeyneyso, kaliya beddel barnaamijka kantaroolka nambarada, waxaa lagu dabaqi karaa in la gooyo qaybo ka mid ah qaabab kala duwan, labadaba goynta laba-geesoodka ah iyo goynta saddex-geesoodka ah ayaa la gaari karaa.
3, Xawaaraha gooyntu waa dhakhso: maaddadu uma baahna in lagu hagaajiyo goynta laysarka, taas oo badbaadin karta qalabka iyo badbaadinta wakhtiga kaalmaynta ee dejinta iyo dejinta.
4, goynta aan xiriir la lahayn: Tooshka goynta laser iyo workpiece xiriir la'aan, ma jiro qalab xiran. Qaybaha farsamaynta ee qaababka kala duwan, uma baahna in la beddelo "qalabka", kaliya beddel xuduudaha wax soo saarka ee laysarka. Habka goynta laserku wuxuu leeyahay qaylo hoose, gariir hoose iyo wasakh la'aan.
5, waxaa jira noocyo badan oo qalab goynta ah: qalabyo kala duwan, sababtoo ah sifooyinka jirkooda kulaylka iyo heerarka nuugista kala duwan ee laser, waxay muujinayaan la qabsiga goynta laser kala duwan.
