What should we know about vias in Circuit Board manufacturing?

2020-09-09

Through Vias, means the via pass through the whole board, from the bottom side to the top side. It is widely existed on all of the double or multilayers PCB.
Blind Vias, means the via connects an ou......

What is the difference for TG130-140/TG150/TG170 FR-4 material?

2020-09-01

The major factor to consider which Tg material to use is the working temperature. If it is working on normal environment, less than 100°C,then you can use normal TG between 130-140°C. If it’s less th......

Why We need high reliability PCB?

2020-07-24

High reliability is a practical science that combines "engineering technology" and "management art". To produce high-reliability PCBs steadily, a set of "standardized, efficient, collaborative, and co......

Rule Setting of Line Width and Line Spacing in PCB Design

2020-06-03

Signal lines that need impedance should be set strictly according to the line width and line spacing calculated by the stack. Such as RF signal (conventional 50R control), important single-ended 50R,......

The Reason the Circuit on the Circuit Board is Designed to Bent

2020-06-03

We found that the circuits on the board were all bent. Why should it be designed like this? Do you know the answer?
