Nov 13, 2024 · The gang mask shape is a critical component in the PCB design, allowing designers to improve efficiency and accuracy. By preventing solder bridging and isolating the pins, designers can ensure that the system has optimal performance, durability, and …

Jan 9, 2025 · In this article we will focus on the minimum solder mask web (sliver) and gang masking. The solder mask swell sizes range from 0.05 – 0.10, but in a typical CAD library, all the solder mask swell sizes are the same value for consistency.

The gang solder mask window will normally be able to be manufactured by screen printing, using a 0.38 mm spacing; however, the pocket solder mask type will require clearances of 75–125 µm, and must therefore be made with photoimageable resist.

Block (Gang) Relief No mask is printed between copper pads. Copper to copper spacing is too tight to reliably print mask between the pads.

Apr 22, 2014 · Gang mask is a term used to describe removing the soldermask between closed spaced pins. Here is and example of a gang masked (SOIC, SOP) with a pin to pin pitch of 0.65mm.

May 4, 2021 · Gang Masking May Be Necessary for Tight Component Spacing: When copper spacing is too tight to hold the minimum 0.004" solder mask web, gang masking (removing the mask between pads entirely) is preferred to prevent flaking and soldering issues during assembly.

Learn about solder masks in PCB manufacturing and their importance in protecting circuits. Discover how PCB Prime uses solder masks to ensure performance for custom PCBs.

If the minimum values for solder-stop clearance (50μm) and solder-stop bridge (100μm) are undercut, the complete solder-stop bridge is omitted (so-called gang mask opening). This is done automatically during the Design Rule Check of your production data.

Dec 21, 2023 · Solder mask is a thin polymer layer on a PCB that insulates the copper traces on a PCB. Implement these DFM tips for a perfect solder mask.

Oct 10, 2023 · Solder mask is an essential protective coating in printed circuit board (PCB) manufacturing. Applying a solder resist provides several key benefits: Insulation: The solder mask layer insulates the board and prevents shorts between closely spaced traces or pads, thus improving electrical reliability.
