As an electronic engineer, designing circuits is a necessary and hard skill, but no matter how perfect the principle design is, if the circuit board design is unreasonable, the performance will be greatly reduced, and in serious cases, it may not even work properly. No matter what software is used, there is a general procedure […]
1. Red glue Red glue is a polyolefin compound that easily solidifies when heated. When the temperature reaches the freezing point of 150°C, red glue begins to change from a paste to a solid. This characteristic can be used for dispensing or printing. To fix the chip components, the circuit board components can be heated […]

First, let us understand the advantages of high frequency microwave circuit boards. High-frequency […]
In today’s era of rapid technological development, rigid printed circuit boards have become an indispensable part of electronic products. So, what exactly is a rigid printed circuit board? What is a rigid printed circuit board? Rigid printed circuit board is an electronic component composed of an insulating substrate, a conductor layer and a copper clad […]
1. Reduce the impact of temperature on circuit board stress Since “temperature” is the main source of circuit board stress, as long as the temperature of the reflow oven is lowered or the speed of heating and cooling of the circuit board in the reflow oven is slowed down, the bending and warping of the […]
PCB circuit board parameters 1. ∑ Dielectric constant (DK value): Usually represents the ability of a certain material to store electrical energy. The smaller the ∑ value, the smaller the ability to store electrical energy and the faster the transmission speed. 2. TG (glass transition temperature): When the temperature rises to a certain area, the […]
