I-stencil yensimbi ye-PCBingahlukaniswa ngezinhlobo ezilandelayo ngokuya ngenqubo:
1. I-stencil yokunamathisela ye-solder: Njengoba igama liphakamisa, isetshenziselwa ukufaka unamathisele we-solder. Baza izimbobo ocezwini lwensimbi oluhambisana namaphedi ebhodini le-PCB. Bese usebenzisa i-solder paste ukuze uphrinte iphedi ebhodini le-PCB ngokusebenzisa i-stencil. Lapho uphrinta unamathisele we-solder, sebenzisa unamathisele we-solder phezulu kwe-stencil, bese ubeka ibhodi lesifunda ngaphansi kwe-stencil. Bese usebenzisa i-scraper ukuze ukhuhle unamathisele we-solder ngokulinganayo phezu kwezimbobo ze-stencil (i-solder paste izogeleza iphuma ku-stencil lapho incishiwe) yehla nge-mesh bese uvala ibhodi lesifunda). Namathisela izingxenye ze-SMD futhi uzigeleze kabusha ndawonye, futhi izingxenye ze-plug-in zishiselwa ngesandla.
2. I-stencil yensimbi yepulasitiki ebomvu: Imbobo ivulwa phakathi kwamaphedi amabili engxenye ngokwesayizi nohlobo lwengxenye. Sebenzisa i-dispensing (ukukhipha ukusebenzisa umoya ocindezelwe ukukhomba ingcina ebomvu ku-substrate ngekhanda elikhethekile lokukhipha) ukuze ubeke ingcina ebomvu ebhodini le-PCB ngensimbi yensimbi. Bese ubeka izingxenye, futhi ngemva kokuba izingxenye zinamathiselwe ngokuqinile ku-PCB, xhuma izingxenye ze-plug-in bese udlula ekufakweni kwamagagasi.
3. I-stencil yenqubo ekabili: Uma ibhodi le-PCB lidinga ukupendwe nge-solder paste neglue ebomvu, kuzomele kusetshenziswe i-stencil enezinqubo ezimbili. I-Dual process metal mesh iqukethe amameshi amabili ensimbi, i-laser steel mesh eyodwa evamile kanye nesitebhisi esisodwa sensimbi. Unganquma kanjani ukuthi kufanele usebenzise i-stencil yesitebhisi yokunamathisela i-solder noma i-stencil yesitebhisi seglue ebomvu? Okokuqala qonda ukuthi kufanele usebenzise i-solder paste noma iglue ebomvu kuqala. Uma i-solder paste isetshenziswa kuqala, khona-ke i-stencil yokunamathisela ye-solder izokwenziwa i-stencil ye-laser evamile, futhi i-stencil yeglue ebomvu izokwenziwa ibe yi-stencil yesitebhisi. Uma usebenzisa i-glue ebomvu kuqala, khona-ke i-stencil yeglue ebomvu izokwenziwa ibe i-laser stencil evamile, futhi i-solder pastencil izokwenziwa ibe yi-stencil yesitebhisi.
