Blind buried through hole circuit board (HDI circuit board) PCB manufacturing three key
HDI board is one of the most precise PCB board, and its process is also more complex. The core steps include the formation of high precision printed circuit, the processing of micro through hole, the plating of surface and hole.
There are several processes of sun block welding for PCB circuit boards
Sunblock welding process can be roughly divided into three operating procedures:The first step is exposure. The second step is developing. The third operation process repair board.
Design of PCB Roche coil and integral circuit board
In this paper, the design of PCB Roche coil and integral circuit board will be introduced in detail, the frequency characteristics of the system will be analyzed by PSpice simulation software, and the existing experimental conditions will be used to build
Explain PCB high frequency board and classification
The presets need to contain both electrical and structural reliability. Generally in the preset very high speed PCB wrench (greater than GHz frequency) this board problem will be relatively tight.
Chinese PCB is in the critical period of iteration upgrade
At present, the global PCB enterprises are mainly distributed in China, Japan, South Korea and other places. The downstream application field of PCB industry is very wide, which is less affected by a single industry, so it is relatively dispersed, with ma
Why do we need solder resistance layer and electroplating gold and silver on PCB board?
PCB surface needs to be welded components, so a part of the copper layer needs to be exposed for welding. These exposed layers of copper are called pads. The pad is generally rectangular or circular, and the area is small.
The PCB coil is used as the sensing element of the LDC1000 inductor-to-digital converter
Series inductors should not be used as secondary sensors, so they must be physically isolated from nearby movable conductive materials, or a shielded SMD inductor must be used.
Types and design standards of pad in PCB design
ad is a very important concept, PCB engineers must be familiar with it. although familiar, many engineers on the pad knowledge is only a little. The types and design standards of pad in PCB design will be introduced in detail below.
What are the requirements of PCB design for PCBA board processing?
At this stage, we move from written blueprints to physical representations constructed using laminate or ceramic materials. Some of the more complex applications require flexible PCBS when particularly compact Spaces are required.
What are the advantages of PCB Mosaic proofing?
In the consultation of many customers, questions about PCB assembling board proofing are often asked. Of course, there are a lot of new customers for PCBA plate proofing is not very understanding.
What are the causes of PCB board deformation
In PCB proofing, how to reduce or eliminate the deformation caused by different material characteristics or processing has become one of the most complicated problems faced by PCB manufacturers.
