PCB karfe stencilana iya raba su zuwa nau'ikan masu zuwa bisa ga tsari:

1. Solder paste stencil: Kamar yadda sunan ya nuna, ana amfani da shi wajen shafa man shafawa. A sassaƙa ramuka a cikin ɗan ƙaramin ƙarfe wanda ya dace da pads akan allon PCB. Sannan yi amfani da manna solder don buga kumfa akan allon PCB ta stencil. Lokacin buga manna mai siyarwa, yi amfani da manna solder a saman stencil, kuma sanya allon kewayawa a ƙasa da stencil. Sa'an nan kuma yi amfani da scraper don goge man siyar a ko'ina a kan ramukan stencil (manna mai siyarwa zai gudana daga cikin stencil lokacin da aka matse shi) yana gangarowa ƙasa da raga kuma a rufe allon kewaye). Haɗa abubuwan haɗin SMD kuma sake juye su tare, kuma abubuwan toshe-in ɗin ana walda su da hannu.

2. Jan roba karfe stencil: Ramin yana buɗe tsakanin pads biyu na bangaren gwargwadon girman da nau'in sashin. Yi amfani da rarrabawa (abin da ake bayarwa shine amfani da iska mai matsewa don nuna jan manne akan maɗaurin ta hanyar kai na musamman) don sanya manne ja akan allon PCB ta cikin ragamar karfe. Sa'an nan kuma sanya abubuwan da aka gyara, kuma bayan an haɗa abubuwan da aka haɗa zuwa PCB, toshe abubuwan da aka haɗa kuma ku bi ta hanyar sayar da igiyar ruwa.

3. Dual-process stencil: Lokacin da allon PCB yana buƙatar fenti tare da manna solder da jan manna, to ana buƙatar amfani da stencil mai aiki biyu. Dual tsari karfe raga kunshi biyu karfe raga, daya talakawa Laser karfe raga da daya tsani karfe raga. Yadda za a ƙayyade ko za a yi amfani da stencil na tsani don manna solder ko stencil don manne ja? Da farko gane ko za a fara shafa solder manna ko jan manna tukuna. Idan aka fara shafa man siyar, to, za a sanya stencil ɗin ɗin ya zama stencil na Laser na yau da kullun, sannan jan manne stencil ɗin za a yi shi ya zama stencil ɗin tsani. Idan ka fara shafa jan manne, to, za a yi jan sulke ta zama stencil na Laser na yau da kullun, sannan za a mai da stencil ɗin da ake solder ɗin ya zama stencil ɗin tsani.
