Ngokwenqubo, i-pcb stencil ingahlukaniswa ngezigaba ezilandelayo:
1. I-stencil yokunamathisela ye-solder: Njengoba igama liphakamisa, isetshenziselwa ukuxubha unamathisele we-solder. Baza izimbobo ocezwini lwensimbi oluhambisana namaphedi ebhodi le-pcb. Bese usebenzisa i-solder paste ukuze unamathisele ebhodini le-PCB ngokusebenzisa i-stencil. Lapho uphrinta unamathisele we-solder, sebenzisa unamathisele we-solder phezulu kwe-stencil, kuyilapho ibhodi lesifunda libekwe ngaphansi kwe-stencil, bese usebenzisa i-scraper ukuze usule unamathisele we-solder ngokulinganayo emigodini ye-stencil (i-solder paste izocindezelwa insimbi yensimbi igeleza phansi enezikhala bese ivala ibhodi lesifunda). Namathisela izingxenye ze-SMD, futhi i-reflow soldering ingenziwa ngokufanayo, futhi izingxenye ze-plug-in zithengiswa ngesandla.
2. I-stencil yepulasitiki ebomvu: Ukuvula kuvulwa phakathi kwamaphedi amabili wengxenye ngokusho kobukhulu nohlobo lwengxenye. Sebenzisa ukusabalalisa (ukukhipha kuwukusebenzisa umoya ocindezelwe ukukhomba ingcina ebomvu ku-substrate ngekhanda elikhethekile lokukhipha) ukuze ukhombe ingcina ebomvu ebhodini le-PCB ngensimbi yensimbi. Bese umaka izingxenye, futhi ngemva kokuba izingxenye zinamathiselwe ngokuqinile ku-PCB, xhuma izingxenye ze-plug-in bese udlulisa i-wave soldering ndawonye.
3. I-stencil yezinqubo ezimbili: Uma i-PCB idinga ukuxutshwa nge-solder paste neglue ebomvu, kuzomele kusetshenziswe i-stencil yezinqubo ezimbili. I-double-process stencil yakhiwe ngama-stencil amabili, i-laser stencil eyodwa evamile kanye ne-steped stencil eyodwa. Unganquma kanjani ukuthi ungasebenzisa i-stencil ene-steped noma iglue ebomvu yokunamathisela i-solder? Okokuqala qonda ukuthi ukuxubha unamathisele we-solder noma iglue ebomvu kuqala. Uma i-solder paste isetshenziswa kuqala, khona-ke i-stencil yokunamathisela ye-solder yenziwa i-stencil ye-laser evamile, futhi i-stencil yeglue ebomvu yenziwa i-stencil enezinyathelo. Uma i-glue ebomvu isetshenziswa kuqala, khona-ke i-stencil yeglue ebomvu yenziwa i-laser stencil evamile, futhi i-solder pastencil yenziwa i-stencil enezinyathelo.
