Ngokwenqubo, i-PCB Sterencil ingahlukaniswa ngezigaba ezilandelayo:

1. I-solder paste Stencil: Njengoba igama libonisa, lisetshenziselwa ukuxubha i-solder aste. Izimbobo ze-Carve ecebeni lensimbi elihambelana namaphakethe ebhodi le-PCB. Ngemuva kwalokho sebenzisa unamathisele we-solder ukuze ugobe kwi-PCB Board ngokusebenzisa i-stencil. Lapho unamathisela umthengisi we-soler, faka unambithe lothengisi phezulu kwe-stencil, ngenkathi ibhodi yesekethe libekwe ngaphansi kwe-stencil, bese lisebenzisa i-scrape yokuqamba izimbobo ze-stencil (unamathisele i-mesh yensimbi. Namathisela izingxenye ze-SMD, futhi uphinde ubonise ukuthengisa kungenziwa ngokufana, futhi izakhi ze-plug-in zithengiswe ngesandla.

2. I-Red Plastic Stencil: Ukuvulwa kuvulwa phakathi kwamaphini amabili engxenye ngokuya ngosayizi nohlobo lwengxenye. Sebenzisa ukusabalalisa (ukusabalalisa ukusebenzisa umoya ocindezelwe ukukhomba i-glue ebomvu ku-substrate ngekhanda elikhethekile lokuhambisa) ukukhomba i-glue ebomvu kwi-PCB Board ngokusebenzisa i-PCB Board kwi-PCB MESH. Bese ubeka uphawu ezingxenyeni, futhi ngemuva kokuthi izakhi zinamathele ngokuqinile kwi-PCB, zixhume izingxenye ze-plug-in bese zidlula i-wave soldering ndawonye.

I-3. I-Stencil yenqubo emibili: Lapho i-PCB idinga ukuxutshwa nge-sorder passe kanye ne-glue ebomvu, khona-ke i-stencil yenqubo emibili idinga ukusetshenziswa. I-stencil yenqubo embaxambili yakhiwa ama-stencils amabili, i-lestencil eyodwa evamile ye-laser kanye ne-stencil eyodwa. Unganquma kanjani ukuthi usebenzisa i-stencil noma i-glue ebomvu ye-solder paste? Okokuqala ukuqonda ukuthi ukuxubha i-brow solde noma i-glue ebomvu kuqala. Uma unamathisela we-solder usetshenzisiwe kuqala, khona-ke i-Stencil Stencil yenziwa nge-Laser Stencil ejwayelekile, kanye ne-glue glue yenziwe nge-stencil ebomvu. Uma i-glue ebomvu isetshenziswa kuqala, khona-ke i-Red Glue Stencil yenziwa nge-Laser Stencil ejwayelekile, futhi i-solder paste ye-solse yenziwa nge-stencil engene.
