Plugged Vias

Plugged Vias. We will need to know the quantity sizes and locations of the vias to be plugged so we can be sure all the required holes are plugged Via Tenting Plugging and Filling Section 1 Via Tenting 2Mask (LPI) Plugged Vias (NonConductive Fill) 3 Via In Pad (Active Pad) 4 Conductive vs NonConductive Filled Vias.

With a mask plugged via (aka Mask Filled or NonConductive Filled via) specific measures are taken to ensure the via is plugged and sealed with mask and the annular ring is covered A common application for this is on a BGA design where vias are commonly found in very close proximity to the BGA’s SMD pads.

Via Protection in PCB: Via Tenting, Via Plugging MADPCB

Via plugging facilitates routing of additional conductor traces between BGA vias amongst other things Filled & Capped Vias are also possible for Blind Vias Application Space saving Protection of solder floating up to the component side Protection of.

Plugged Vias Plugging (with planarization and overplating) is alternate option If vias must be drilled through component mounting pads on a high density PCB the plugs can be drawn down to completely fill the vias The surface is then planarized and plated over so that the pads can be used for soldering.

Via Plugging Process Description The primary challenge is trying to force the required volume of ink into that small of a hole To get a better understanding of the challenge it is important to understand the process by which the ink is applied The first step is to create a screen through which the plugging ink is passed into the hole.
