一文搞懂PCB阻焊层和助焊层的区别. 文/ 中信华PCB. . 阻焊层：solder mask，是指板子上要上绿油的部分；因为它是负片输出，所以实际上有 solder mask 的部分实际效果并不上绿油，而是镀锡，呈银白色！

2023年10月10日 · In this comprehensive guide, we will explain in detail what a solder mask on PCB is, the different types available, and how it critically impacts the reliability and lifespan of your PCBs. Read on to learn their essential functions and why proper solder mask coverage and selection is vital for application-specific requirements.

The best method of prolonging the PCB’s lifespan is applying a protective coating known as a solder mask on the PCB surface. This article offers a comprehensive analysis of solder mask and how you can use it to inhibit problems, like solder mask relief.

2017年10月17日 · Solder masks protects metal elements on a PCB from oxidation and electrical "bridging" between solder pads. Learn about the best solder stop mask PCB approach for your project.

2024年8月28日 · Solder mask, the thin polymer layer applied to printed circuit boards (PCBs), plays a crucial role in modern electronics manufacturing. This protective coating shields copper traces from oxidation, prevents solder bridges during assembly and enhances the overall durability of electronic devices.

2025年1月9日 · Learn how to protect your printed circuit board with a solder mask in this comprehensive guide from TechSparks. Discover the benefits of applying a solder mask in PCB, including protection against short circuits and corrosion. Explore design guidelines, tenting vias, solder mask gaps, and more.

2024年3月14日 · In this blog, I’ll discuss the various aspects of solder mask (also known as solder resist or solder mask varnish) for PCBs. Specifically, my focus will centre on Liquid Photo Imageable solder mask – LPI, exploring its composition, functions, and crucial considerations for both buyers and technicians involved in PCB production.

2023年12月25日 · What is a PCB Solder Mask? The PCB Solder Mask is a thin copper trace layer applied to the printed circuit board’s top and bottom sides. It protects the PCB against oxidations and prevents the formation of solder bridges in between the solder pads.

5 天之前 · Below is a comparison of solder mask application process steps, conventional vs. inkjet. 1. Data Preparation. The PCB solder mask process begins with preparing the necessary design files and verifying they are accurate and complete. The data includes the layout of the PCB, the areas to be masked, and the areas to be left exposed for soldering.

PCB soldermask, also known as solder resist or solder stop, is a critical component of PCBs. It is a thin, protective layer of polymer material that is applied to the surface of the PCB, serving as a barrier against various elements, such as moisture, dust, and oxidation.
