Everyone knows that PCBs are easy to be bended or warped when get through the reflow furnace. So how to avoid this situation, here are some advices for you.1. Reduce the effect of temperature on PCB board stress Since the "temperature" is the main source of stress in the board, as long as the temperature of the reflow furnace is lowered or slow the speed of warming up and cooling down in the reflow furnace, the board bending and the board warping can be greatly reduced. However, there ...

There are four main types of plating methods in PCB (Printed Circuit Board) production: finger-plated plating, through-hole plating, reel linkage selective plating and brushing plating. Here's a brief introduction: 1. Finger-plated platingRare metals need to be plated on the board edge connectors, board edge joint or gold fingers to provide lower contact resistance and higher abrasive resistance. This technique is known as finger-plated or protruding partial plating. Gold is often plated on ...

By Hesam Moshiri, Anson BaoDisclaimer: This circuit is connected directly to the mains voltage. You must care about all safety precautions before using the device. AC loads are everywhere around us because at least home appliances are supplied with the mains power. Therefore, we always face the situations that we want to have full control (dimming) over an AC load such as a lamp, a motor, vacuum cleaner … etc. We should know that controlling an AC load is not identical with a DC load. So we shou...
