Product introduction:The bridge is a new generation of component parameter measuring instrument, using the latest testing technology in this field. The powerful test function and superior measurement performance make the product squeeze into the internati
The temperature range can be automatically selected. It has its own refrigeration system, without external circulating water cooling device, and adopts stainless steel water pump, so that the noise is reduced and the generation of rust is eliminated, avoi
How to improve the welding hole of PCBA:(1) The PCB and parts will be exposed in the air for a long time to avoid moisture, (2) control the welding paste with moisture, It is very easy to cause skin pores and tin beads, (3) the environmental humidity cont
In the high frequency circuit, the noise of the power supply has an obvious influence on the high frequency signal. Therefore, the first requirement is that the power supply be low noise. Clean land is just as important here as clean power.
Ordinary Tg sheet is above 130 degrees, High-Tg is generally above 170 degrees, and medium Tg is above 150 degrees. The Tg of the substrate has been improved, covering heat resistance, moisture resistance, chemical resistance, stability and so on.
The more the number of signal networks, the higher the density of the device, the higher the PIN density, the higher the frequency of the signal design should be adopted as far as possible.
This paper introduces the PCB board copying industry will be involved in the future technology Wi-Fi 6 RF technology.
The process of moving a program to the internal storage space of the chip is generally divided into offline burning and online burning offline burning. These chips are compatible with chips in different packages through various adapters, and the chips can
which is equivalent to reviewing the schematic diagram, modifying the scheme for design, and si simulation at the same time. There are many types of power supply with small voltage and large current on the board.
The most important material for printed circuit boards is copper, from which most boards are made.
ERP project implementation success depends on three points of technology, seven points of management, twelve points of data. Visible, ERP system in the importance of basic data collation.
How to ensure the quality of the patch: 1. Strict SOP production process control; 2. Professional technical team; 3. Complete incoming material inspection and confirmation process; check PCB and materials; 4. PCBA new machine type production project team;
