Istencil yentsimbi yePCBzinokwahlulwa ngokwezi ntlobo zilandelayo ngokwenkqubo:

1. I-stencil yokuncamathelisa ye-Solder: Njengoko igama libonisa, isetyenziselwa ukufaka i-solder paste. Ukukrola imingxunya kwiqhekeza lentsimbi elihambelana neepads kwibhodi yePCB. Emva koko sebenzisa i-solder paste ukuprinta iphedi kwibhodi yePCB ngokusebenzisa istensile. Xa uprinta i-solder paste, sebenzisa i-solder paste phezulu kwi-stencil, kwaye ubeke ibhodi yesiphaluka ngaphantsi kwe-stencil. Emva koko sebenzisa i-scraper ukukrazula intlama ye-solder ngokulinganayo phezu kwemingxuma ye-stencil (i-solder paste iya kuphuma kwi-stencil xa icinezelwe) yehla kwi-mesh kwaye igqume ibhodi yesekethe). Qhoboshela amacandelo e-SMD kwaye uwajikelezise kwakhona kunye, kunye nezixhobo zeplagi zidityaniswe ngesandla.

2. Istencil yentsimbi yeplastiki ebomvu: Umngxuma uvulwa phakathi kweepadi ezimbini zecandelo ngokobukhulu kunye nohlobo lwenxalenye. Sebenzisa i-dipensing (i-dispensing kukusebenzisa umoya ocinezelweyo ukukhomba iglu ebomvu kwi-substrate ngentloko ekhethekileyo yokukhupha) ukubeka iglu ebomvu kwibhodi ye-PCB ngokusebenzisa i-mesh yensimbi. Emva koko beka amacandelo, kwaye emva kokuba amacandelo ancanyathiselwe ngokuqinileyo kwi-PCB, iplagi kwiikhomponenti zeplagi kwaye uhambe nge-soldering yamaza.

3. Istencil yenkqubo ephindwe kabini: Xa ibhodi yePCB ifuna ukupeyintwa nge-solder paste kunye neglu ebomvu, emva koko kufuneka kusetyenziswe i-stencil yenkqubo ezimbini. Umnatha wentsimbi osebenza kabini unemingxuma emibini yentsimbi, umnatha wentsimbi oqhelekileyo welaser kunye neleli enye yentsimbi. Indlela yokufumanisa ukuba usebenzisa i-stencil ye-ladder kwi-solder paste okanye i-stencil ye-ladder yeglue ebomvu? Okokuqala qonda ukuba usebenzisa i-solder paste okanye iglue ebomvu kuqala. Ukuba i-solder paste isetyenziswe kuqala, ngoko i-solder paste stencil iya kwenziwa kwi-stencil ye-laser eqhelekileyo, kwaye i-stencil yeglue ebomvu iya kwenziwa kwi-stencil ye-ladder. Ukuba usebenzisa i-glue ebomvu kuqala, ke i-stencil yeglue ebomvu iya kwenziwa ibe yi-stencil ye-laser eqhelekileyo, kwaye i-solder pastencil iya kwenziwa kwi-stencil ye-ladder.
