PCB ígwè stencilenwere ike kewaa n'ime ụdị ndị a dịka usoro:

1. Solder tapawa stencil: Dị ka aha ahụ na-egosi, a na-eji ya na-etinye tapawa solder. Kpoo oghere n'ime mpempe ígwè kwekọrọ na pads dị na bọọdụ PCB. Mgbe ahụ, jiri tapawa na-ere ihe iji bipụta ya na bọọdụ PCB site na stencil. Mgbe ị na-ebi akwụkwọ tapawa, tinye ihe nkedo n'elu stencil, ma tinye bọọdụ sekit n'okpuru stencil. Mgbe ahụ, jiri scraper kpochapu ihe nkedo nke na-eme ka ọ bụrụ nke ọma n'elu oghere stencil (ihe nkedo ahụ ga-esi na stencil ahụ pụta mgbe a na-agbanye ya) na-agbada na ntupu ma kpuchie bọọdụ sekit). Gbakwunye akụrụngwa SMD wee megharịa ha ọnụ, na ihe nkwụnye nkwụnye na-eji aka agbado ya.

2. Red plastic steel stencil: A na-emeghe oghere n'etiti paịlị abụọ nke akụrụngwa dịka nha na ụdị nke akụkụ ahụ. Jiri ihe na-ekesa (nke na-enye bụ iji ikuku abịakọrọ na-arụtụ aka na-acha uhie uhie n'elu mkpụrụ site na isi ihe pụrụ iche) iji tinye gluu na-acha uhie uhie na osisi PCB site na nchara ígwè. Mgbe ahụ, tinye ihe ndị ahụ, na mgbe a na-ejikọta ihe ndị ahụ na PCB, gbanye ihe nkwụnye ahụ wee banye n'ịzụ mmiri.

3. Dual-process stencil: Mgbe a PCB osisi kwesịrị ka e jiri solder mado na-acha uhie uhie gluu, mgbe ahụ a dual-process stencil kwesịrị iji. Dual usoro ígwè ntupu mejupụtara abụọ ígwè meshes, otu nkịtị laser ígwè ntupu na otu ubube ígwè ntupu. Kedu otu esi ekpebi ma ị ga-eji stencil ubube maka mado solder ma ọ bụ stencil ubube maka gluu uhie? Buru ụzọ ghọta ma ị ga-ebu ụzọ tinye tapawa solder ma ọ bụ gluu uhie. Ọ bụrụ na a na-ebu ụzọ tinye pasta ahụ, mgbe ahụ, a ga-eme stencil nke na-ere ihe ka ọ bụrụ stencil laser nkịtị, a ga-emekwa stencil na-acha uhie uhie ka ọ bụrụ stencil ubube. Ọ bụrụ na i buru ụzọ tinye gluu na-acha uhie uhie, mgbe ahụ, a ga-eme stencil na-acha uhie uhie ka ọ bụrụ stencil laser nkịtị, a ga-emekwa stencil nke na-ere ihe ka ọ bụrụ stencil ubube.
