Dịka usoro a si dị, enwere ike kewaa pcb stencil n'ụdị ndị a:

1. Solder tapawa stencil: Dị ka aha ahụ na-egosi, a na-eji ya eme ihe na-ehicha ihe.Kpoo oghere n'ime mpempe ígwè kwekọrọ na pads nke bọọdụ pcb.Mgbe ahụ, jiri mado na-ere ihe na-etinye na bọọdụ PCB site na stencil.Mgbe ị na-ebi akwụkwọ tapawa, tinye ihe nkedo n'elu stencil ahụ, ebe a na-edobe bọọdụ sekit n'okpuru stencil, wee jiri scraper kpochapu tapawa ahụ nke ọma na oghere stencil (a ga-esi na mpempe akwụkwọ ahụ pịpịa ya. Ntupu ígwè. gbadaa ntupu ma kpuchie bọọdụ sekit).Tapawa ihe ndị SMD, na reflow soldering nwere ike ime n'otu n'otu, a na-ejikwa aka na-ere ihe nkwụnye ahụ.

2. stencil plastik na-acha uhie uhie: A na-emeghe oghere n'etiti paịlị abụọ nke akụrụngwa dịka nha na ụdị nke akụkụ ahụ.Jiri ihe na-ekesa (nkesa bụ iji ikuku abịakọrọ na-arụtụ aka na-acha uhie uhie gluu na mkpụrụ site na isi ihe pụrụ iche) iji tụọ gluu uhie na osisi PCB site na nchara ígwè.Mgbe ahụ, kaa akara n'ihe ndị ahụ, ma mgbe a na-ejikọta ihe ndị ahụ na PCB, gbanye ihe nkwụnye ahụ ma gafee ebe a na-ere mmiri ọnụ.

3. Dual-process stencil: Mgbe PCB chọrọ ka e jiri ya mee ihe na tapawa solder na gluu na-acha uhie uhie, mgbe ahụ, ekwesịrị iji stencil dual-process.Stensụl nwere usoro ihe abụọ mejupụtara stencil abụọ, otu stencil laser nkịtị na otu steepụ steepụ.Kedu otu esi ekpebi ma ị ga-eji steepụ steepụ ma ọ bụ gluu na-acha uhie uhie maka tapawa solder?Buru ụzọ ghọta ma ị ga-ebu ụzọ ascha paste solder ma ọ bụ gluu uhie.Ọ bụrụ na a na-ebu ụzọ tinye pasta ahụ, mgbe ahụ, a na-eme stencil nke na-ere ihe ka ọ bụrụ stencil laser nkịtị, a na-emekwa stencil na-acha uhie uhie ka ọ bụrụ stencil steepụ.Ọ bụrụ na a na-ebu ụzọ tinye gluu na-acha uhie uhie, mgbe ahụ, a na-eme stencil na-acha uhie uhie ka ọ bụrụ stencil laser nkịtị, a na-emekwa stencil na-acha uhie uhie ka ọ bụrụ stencil a gbagoro agbago.
