Upstream of PCB, prices of two raw materials continue to rise

The cost of raw materials continues to rise, driving the profitability of copper clad laminates to rise. The price of electronic copper foil, the largest material, is affected by c

Analysis of traditional PCB design methods

The traditional pcb design goes through the process of schematic design, layout design, pcb production, measurement and debugging.

How to prevent others from copying your PCB board?

Grinding the chip, use fine sandpaper to grind off the model on the chip. It is more effective for the chip with partial door

Timing Analysis in High Speed PCB Design

For digital system design engineers, timing analysis is an important part of high-speed PCB design. Especially with the emergence of the 100M bus

Quality assurance of PCB multilayer boards

The quality of PCB multilayer boards is defined in IPC, the surface technology is anti-oxidation, the vacuum packaging is not opened, it will be used up within half a year, and the

Wiring method of PCB multilayer board

Four-layer circuit board wiring method [5]: Generally speaking, a four-layer circuit board can be divided into top layer, bottom layer and two middle layers. The top layer and the

Process flow of PCB multilayer board

1 Process flow The printed circuit board with the prepared graphics → acid degreasing → scanning water washing → secondary countercurrent water washing → micro-etching → scanning w

PCB multi-layer board outsourcing processing requirements

The processing of printed boards [7] is generally external processing, so when providing drawings for external processing, it must be accurate and explain as clearly as possible. A

PCB Multilayer Board Design

1 Determination of the shape, size and number of layers of the board Any printed board has the problem of coordinating with other structural parts. Therefore, the shape and size of

PCB multilayer board features

The biggest difference between PCB multilayer boards and single-sided and double-sided boards is that the internal power layer (maintaining the internal electrical layer) and the g

Current Situation and Development of Multilayer Printed Boards

Since the middle and late 1980s, the output value and output of multi-layer boards have increased by more than 10% (compared with the previous year) every year. Due to the rapid de

Basic concept of pcb multilayer board

PCB multi-layer board refers to the multi-layer circuit board used in electrical products, and the multi-layer board uses more single-sided or double-sided wiring boards. A printed
