What is a tenting via?

What is a tenting via?

Tenting a via refers to covering via with soldermask to enclose or skin over the opening. A via is a hole drilled into the PCB that allows multiple layers on the PCB to be connected to each other. A non-tented via is just a via that is not covered with the soldermask layer.

What is hole plugging?

Via hole plugging is a PCB manufacturing technique in which the via hole is filled with solder mask or epoxy. This process partially or completely closes the via hole using a conductive or non-conductive filling material.

What are the 3 types of hole plugs?

There are different kinds of holes….Hole Plugs – To Seal And To Conceal

• Liquid tight plugs–These are usually oil-tight, rain-tight, and submersible.
• Finishing dome plugs – These come in multiple sizes, colors, and materials, but are mainly used to close no-longer-needed panel holes and actual electrical knockouts.

Which is the easiest way to tent a via?

This is the easiest and least costly process—actually there is no added cost for this process. Simply remove the mask clearances from the vias you wish to have tented. Tenting a via simply means to cover the annular ring and via hole with solder mask. No special steps are taken to ensure the hole opening remains closed.

What’s the difference between via plugging and via tenting?

One of the most confusing concepts in PCB design is the difference between Via Tenting, Via Filling and Via Plugging. Designers often get mixed up between them and fail to take full advantage of the process.

What does it mean to tent a via ring?

Tenting a via simply means to cover the annular ring and via hole with solder mask. No special steps are taken to ensure the hole opening remains closed. Tenting a via will sometimes result in the hole remaining covered but it isn’t guaranteed.
