Essential Tips Chem Etching Design Engineers Should Know: Tabs & Tie Ins

This is the third post in a series of four that discusses essential tips that design engineers should know in order to create better photo etching designs.

Last week, we discussed some tips for how engineers can achieve diverse hole configurations in photo chemical etching.

This week, we’ll discuss the subject of tabs.

Tabbing generally involves extending one or more lines from the part to the surrounding metal border. This means the part remains partially attached to the source material.

Ideally, we recommend avoiding tabs and tie-ins altogether. The very nature of tabbing defeats one of the primary advantages of photo chemical etching: a burr free design.

That said, sometimes designers must use tabbing. We see it most commonly with very small parts that need a secondary plating.

Determining when you should use tabbing and when you can avoid it can be challenging. You are always welcome to contact Newcut for a consultation. With decades of experience, our engineers can help you determine the best solutions for your designs.
