PCB board bending or warping is usually caused by: 1. Temperature change: 2. Uneven plating: 3. Uneven PCB board thickness: 4. Improper plate size 5. Uneven welding: 7. Improper PCB board processing: 8. Material problems of PCB board 9. Design problems of
PCB light board shipment inspection items: 1, basic inspection, 2, electrical performance test report, 3, metallographic section analysis report, 4, impedance test
During design, WPC can be designed according to product characteristics to reduce shadow areas and avoid collision parts.
What is printed circuit board DFM: Product Manufacturability Design for short DFM. It is a discipline that studies some design behavior rules of the relationship between the physical design of the product itself and the parts of the manufacturing system,
PCB hard board and FPC soft board difference: 1. Rigid PCB: often used as motherboard, cannot bend, 2. Flexible board: FPC also known as flexible circuit board, can be bent
The performance of PCB board is determined by the material used (high Q value), wiring design and several layers of board. The quality of PCB board has nothing to do with PCB color
There are five common principles in PCB design: component arrangement rules, according to the signal direction layout principle, electromagnetic interference prevention principle, thermal interference suppression principle, adjustable component layout pri
PCBA processing requirements for PCB board; 1, PCB size,2, PCB board side width,3, PCB bending,4, PCB board Mark point,5, PCB welding pad
Especially for automotive electronics, which require high stability of the product, heavy industry is not allowed, so the board after the dust removal process has become a very practical choice
PCB board selection of lead-free spray tin and lead spray tin difference: 1, lead-free spray tin belongs to environmental protection process, does not contain harmful substances "lead", the melting point is about 218 degrees; 2, lead spray tin d...
In order to ensure the smooth completion of the special process and facilitate the PCBA welding process, PCB board must meet the manufacturability requirements in dimensions, pad distance and other aspects
FPCS have many applications in a number of different fields. They are used in solar cells, mobile phones, vehicles and aircraft. Many of these applications require thin and durable flexible sheets, which can therefore withstand bending, folding or rolling
