Minimum solder mask sliver jlcpcb. Either reduce the solder mask openings, provided that they will comply with your manufacturer's specs, or increase them. Ensuring that there is a minimum width of solder mask across the board, this rule checks the distance between any two solder mask openings to ensure that they are equal to or greater than the user-specified value. But now there's only about 0. Sometimes the solder mask consistency leaves something to be desired. In the latter case, you'll lose the benefit of having the solder mask between pins. robertferanec , 02-15-2021, 12:29 AM You can set the rule to 0. 051 mm between each pad's solder mask expansions, and JLCPCB's minimum solder mask bridge is 0. Jan 7, 2025 · JLCPCB lists a solder mask requirement of 0. EEVblog Captcha We have seen a lot of robot like traffic coming from your IP range, please confirm you're not a robot Learn about solder mask, a protective layer applied to printed circuit boards (PCBs) to insulate copper traces and prevent unintended solder connections. A minimum solder mask sliver is the minimum distance between solder mask openings that expose the copper pads on a PCB. Dec 19, 2023 · The minimum solder mask sliver refers to the minimum distance between the resistance welding openings of the exposed copper pad on the PCB. 5 mil), so I rounded up the Solder Mask to 0. Nov 29, 2024 · Which component / package? Pitch? What solder mask expansion did you set? Which solder resist color? With LDI you can have a solder mask expansion of 30um and a web (sliver) of >= 70um. Manufacturers often set minimum solder mask sliver widths to prevent problems such as solder bridging and wicking. Optimize your PCB layout to prevent solder bridging, improve insulation, and enhance reliability while ensuring manufacturability in high-density circuit designs. 051 mm (2 mil). 5/3. So a minimum of 130um between pads (copper). 5 rule seems generous enough, but I worry about the minimum solder mask sliver. 1mm so you will not be getting errors. Solder mask expansion is the deliberate increase of the solder mask opening around a PCB pad to ensure the entire pad is exposed for soldering, compensating for potential misalignment during manufacturing. Minimum Solder Mask Sliver in PCB Design In the realm of Printed Circuit Board (PCB) design and manufacturing, minimum solder mask sliver is a critical parameter that directly influences the reliability and performance of electronic devices. 1 mm.

This technique is essential for creating non-solder mask defined (NSMD) pads, which offer better solder joint reliability. . Apr 24, 2025 · Having issues with your PCB fabrication? Learn how to order boards with solder mask defined pads to get the perfect PCB at JLCPCB. Printed Circuit Board manufacturing and assembly capabilities, PCB technologies or design rules for guide of PCB design and production Feb 7, 2025 · Learn about minimum solder mask sliver requirements, IPC standards, design considerations, and manufacturing challenges. For example, Pin 2, 'SW', is overlapped by both Pin 1 and Pin 3's clearance boundaries. Jun 27, 2024 · However, according to the attached image, the pin's clearance boundaries (0. 2mm according to JLCPCB's assembly capabilities) overlap with adjacent pins. Feb 9, 2021 · On a board that combines TH and SMT parts, if the CM is going to wave solder, you may want the solder side minimum sliver to be larger than the component side minimum sliver. Aug 23, 2018 · Summary This rule helps identify narrow sections of solder mask that may cause manufacturing problems at a later stage. A typical recommendat Aug 31, 2023 · A minimum gap, or sliver, should be maintained between these openings to ensure PCB functionality and reliability. 038 mm (1.
