• You should be familiar with these 10 simple and practical methods for dissipating heat on PCBs.

  For electronic equipment, a certain amount of heat will be generated during operation, which will cause internal temperature of equipment to rise rapidly. If heat is not dissipated in time, equipment will continue to heat up, and ...

• Focus! Don't pull PCB track carelessly

  Blindly pull thread, even pulling is useless! When some small partners do PCB layout, board is ready to go. Due to insufficient or lack of analysis at an early stage, post-processing is difficult. For example, after extruding a ...

• RC downgrade secret, I don't know how many people will be fooled

  I guess a lot of people have a better understanding of what RC step-down is, but they don't show much interest in RC step-down. This is because: Design parameters, as a rule, are far from real test (because idea is wrong, we will ...
