Top Missing Information When Requesting a PCB Quote

Once a circuit board designer prepares the design, the next step is to find a manufacturer to transform it into a finished product. To get the board manufactured, an estimate or a PCB quote needs to be placed. The main intention is to fabricate and assemble a board...

Making Sense of Wave Soldering

Making Sense of Wave Soldering

Depending on component technology, many options exist for automated mass soldering today. But wave soldering was the first – and, for several decades, only – practical method for quickly soldering large numbers of components to printed circuit boards (“PCBs,” also...

How to Mitigate Outgassing Effects in PCBs

PCB outgassing or offgassing is a defect that occurs when air is trapped inside a circuit board during production. The trapped air creates voids or blowholes, which might damage the board's performance. Choosing a low outgassing rate material and vacuum pre-baking are...

What is Solder Mask Layer?

What is Solder Mask Layer?

After PCB fabrication, the copper traces on the board typically face the risk of oxidation and corrosion due to environmental exposure. The most reliable way to prevent this and increase the life of the PCB is to provide a protective coating known as a solder mask...
