在制作PCB时,如果没有设计PCB盖油处理,而且与厂家未说明沟通,正常做出来的板子过孔可能会有不同情况。有些PCB工厂,不论PCB文件本身过孔设计的如何(是否盖油),该工厂也可以直接按客户的备注、批量处理这些过孔。 过孔塞油(Via Plugging) 过孔塞油是将通孔的孔里面用油墨进行塞孔制作,强调的是塞孔的质量和密实度。

導通孔一般都是透光的,也就是當你把PCB拿起來對著燈光,可以看到一些有漏光的小孔大概就是了,而塞孔(plugging)就是要把這些導通孔(vias)給堵起來,讓它不再透光,當然,塞孔的目的不是為了避免透光,PCB塞孔的最大目的是為了避免PCB在SMT及波焊製程時出現不必要的焊接品質問題。當然,PCB上除了導通孔外還有通孔(Throu...

After the hot air leveling, the plug hole process is first produced by the non-plug hole process. After the hot air leveling, the aluminum sheet screen or the ink blocking screen is used to complete the via hole plugging of all the fortresses required by the customer. ...
三.塞孔.减铜及研磨 塞孔(Hole Plugging)埋孔在经过电镀及制作线路后,需要再进行一次压合.如果不进行塞孔,压合时靠外排列的介质将会填入孔内,这存在一定质量风险: a.因胶质填入埋孔内,靠外层压合介质将会偏薄. b.压合时介质填入埋孔,但不能确保将孔内空气完全赶出.如孔内有空气存在, 板子在受热时...
