style="text-indent:25px">SMT貼片膠的使用目的：①波峰焊中防止元器件脫落(波峰焊工藝)。在使用波峰焊時，為防止印制板通過焊料槽時元器件掉落，而將元器件固定在印制板上。②再流焊中防止另一面元器件脫落(雙面再流焊工藝)。雙面再流焊工藝中，為防止已焊好的那一面上大型器件因焊料受熱熔化而脫落，要使有SMT貼片膠。③防止元器件位移與立處(再流焊工藝、預(yù)涂敷工藝)。用于再流焊工藝和預(yù)涂敷工藝中防止貼裝時的位移和立片。④作標(biāo)記(波峰焊、再流焊、預(yù)涂敷)。此外，印制板和元器件批量改變時，用貼片膠作標(biāo)記。SMT貼片加工中焊膏中焊劑含量太高，在回流焊過程中過多的焊劑的流動導(dǎo)致了元器件的移位。肇慶大批量SMT貼片報(bào)價(jià)</p><p
