Surface Finish Considerations The PCB Surface Finish you select may be the most important material decision you make for your electronic assembly. The Surface Finish you select will influence the cost, manufacturability, quality, and reliability of the final product. Just …Read More
The evolution of technology manufacturing is always moving towards a higher level of complexity. Newer designs have to be lighter, faster and smaller with every iteration of the next device. Not only do we continue to move towards more complex …Read More
If you’ve ever had a circuit board professionally manufactured, you have likely been asked your choice between HASL and ENIG surface finishes. From solderability to cost, these two finishes can’t possibly be more different. While some engineers have a tried and true favorite, you may be left...Read More
Due to the specialized nature of hard gold and soft gold surface finishes, many designers never encounter the particular challenges associated with these surface finishes. As a result, the first build for a hard or soft gold PCB can often be cumbersome and even surprising.Read More
Liquid Photoimageable (LPI) Soldermask For many years the only color you would see on a printed circuit board was green. Maybe a military influence? The color of the printed circuit board is only a small part of the consideration for …Read More
