Printed Circuit Board Quality Standards and Performance Specifications Series Manual. Includes the quality standards and performance specifications set by the Printed Circuit Board Association of America for all printed circuit boards.
Many customers will require the production of halogen-free board, halogen-free board is an environmentally friendly material, halogen-free circuit board is used by the substrate is processed with halogen-free raw materials.
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,
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
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
Printed circuit boards consist of electrically conductive tracks that interconnect components on the board. They are also commonly used for electrical safety testing or verification
Why do PCBA circuit board inspection: PCBA inspection is a link in the whole production process of PCBA processing, is an important means to control product quality
The way to distinguish the circuit board is good or bad: 1, light and color, 2, PCB board size and thickness of the standard rules, 3, PCB board weld appearance
Circuit board components testing skills: 1. Measure the polarity of each foot of the rectifier bridge, 2. Judge the quality of crystal vibration, 3. Unidirectional thyristor detection, 4. Polarity recognition of bidirectional thyristors, 5. Check the qual
he system speed can be greatly reduced because of the increase of delay time caused by the delay of 2ns per 30cm line length of the common interconnect on the baseboard. Image shift register synchronization counter.
with the increase of labor cost and raw material price again and again, many customers began to require product price reduction to save costs.
