Why need cover with the gold for the PCB?
1. Surface of PCB: OSP, HASL, Lead-free HASL, Immersion Tin, ENIG, Immersion Silver, Hard gold plating, Plating gold for whole board, gold finger, ENEPIG… OSP: low cost, good solderability, harsh storage conditions, short time, environmental technology, good welding, smooth… HASL: usually it’s m...Read more -
Organic Antioxidant (OSP)
Applicable occasions: It is estimated that about 25%-30% of PCBs currently use the OSP process, and the proportion has been rising (it is likely that the OSP process has now surpassed the spray tin and ranks first). The OSP process can be used on low-tech PCBs or high-tech PCBs, such as single-si...Read more -
WHAT IS A SOLDER BALL DEFECT?
WHAT IS A SOLDER BALL DEFECT? A solder ball is one of the most common reflow defects found when applying surface mount technology to a printed circuit board. True to their name, they are a ball of solder that has separated from the main body that forms the joint fusing surface mount components to...Read more -
HOW TO PREVENT A SOLDER BALL DEFECT
May 18, 2022Blog, Industry News Soldering is an essential step in the creation of printed circuit boards, particularly when applying surface mount technology. Solder acts as a conductive glue that holds these essential components tight onto the surface of a board. But when proper procedures aren’...Read more -
Flaws in U.S. Approach to Electronics Manufacturing Require Urgent Changes, or Nation Will Grow More Reliant on Foreign Suppliers, New Report Says
U.S. circuit board sector is in worse trouble than semiconductors, with potentially dire consequences Jan 24, 2022 The United States has lost its historic dominance in a foundational area of electronics technology – printed circuit boards (PCBs) – and the lack of any significant U.S. Government s...Read more -
Design Requirements for PCB Structures：
Multilayer PCB is mainly composed of copper foil, prepreg, and core board. There are two types of lamination structures, namely, the lamination structure of copper foil and core board and the lamination structure of core board and core board. The copper foil and core board lamination structure is...Read more -
What problems should be paid attention to when designing FPC flexible board?
FPC flexible board is a form of circuit fabricated on a flexible finish surface, with or without a cover layer (usually used to protect FPC circuits). Because FPC soft board can be bent, folded or repeated movement in a variety of ways, compared with ordinary hard board (PCB), has the advantages...Read more -
