What are the specifications of Mark processing steps: 1. The processing method of Mark, whether Mark is needed, which side of the template, etc. 2. Which side of the template Mark graphics should be placed according to the specific structure of the printi
Drawing pads with filler blocks can pass DRC inspection when designing lines, but it is not feasible for machining. Therefore, similar pads cannot directly generate solder resistance data.
We should start from the design of PCBA lead-free products to consider the compatibility between lead-free materials, lead-free and design, lead-free and process compatibility; Give full consideration to heat dissipation; Carefully select PCB board, pad s
ISO9001 certification, CCC certification is the basic certification of PCBA manufacturers, can obtain ISO13485, IATF16949, UL certification of PCBA manufacturers are more comprehensive strength of the enterprise.
With sufficient theoretical basis, more practice, more learning, more summary, in order to be qualified for the PCBA circuit board maintenance post.
PCBA refers to a machining process, and the process on PCB board has been completed before it is calculated as PCBA. PCB refers to a blank printed circuit board without any parts, that is, PCBA is a finished board, PCB is a bare board.
PCB performance test is a necessary test to ensure the stability of product performance after processing. It is divided into different tests according to the actual environment and purpose of product use.
Under proper working conditions, most electronic devices can have a life expectancy of decades or more, but some still fail prematurely. The reason is often the stress of not being noticed.
pad according to pad, this is the plug-in hole, via you have two choices, if you provide the original file, you can choose when placing the order, if you provide the gerber file, please check whether the gerber file meets your requirements!
Original water tank - stainless steel booster pump - multi-media filter - activated carbon filter - precision filter - reverse osmosis host - pure water tank - water point
The battery of electric car can be said to be the most important, but many people do not care about it, but will complain about their electric car battery is not good, and the main reason is because of improper maintenance skills, resulting in premature b
Printed circuit board, also known as printed circuit board, printed circuit board, shortened to build and circuit board, often use English (PCB Printed circuit board) or write PWB (Printed wire board), printed with insulation board as the base material, c
