How to prevent PCB board warping?
One of the causes of PCB warping is that the substrate used may warpage, but in the process of PCB processing, due to thermal stress, chemical factors, and improper production process will also cause PCB warpage.

Automotive PCB industry: smart electric drive to a bright future
The automotive PCB market is benefiting from the increasing electronization of vehicles as consumers demand more functionality and safety.
Reliability design of PCB circuit board routing
Width and spacing of printed wire are important design parameters, which affect not only the electrical performance and electromagnetic compatibility of PCB board, but also the manufacturability and reliability of PCB board.
How to calculate the cost of PCB copy board?
What do PCB copying boards need to provide: Usually, simple single and double panel copying boards only need to provide one set of samples. If it is multi-layer board, it is better to provide two sets of exactly the same samples, which is convenient for l
PCBA processing wave soldering points for attention
PCBA processing wave welding notes :PCBA after wave welding, cleaning board, storage and maintenance may be white around the pad. The white stuff is mostly residue
How to select components and substrates in PCBA processing?
SMT factory layout and location requirements: 1, fire extinguisher placement area, 2, material rack car placement area, 3, material preparation table placement area, 4, printing station table placement area, 5, tin paste placement area, 6, after the furna
What preliminary work needs to be done before PCB design
Preliminary work to be done before PCB design :1, determine the number of PCB layers, 2, PCB design rules and restrictions, 3, component layout
How to control creepage distance and clearance distance in high voltage PCB design?
Spacing is more important in high voltage designs because the voltage across the board components makes arcing between the two conducting components more likely to occur on your PCB. Any electric arcs that do occur pose a higher risk to both the product a
PCBA contract material processing factory
PCBA contracted work and materials matters needing attention :1. Circuit design; 2. Selection of materials; 3. Selection of PCBA factory
PCBA manufacturers detailed circuit board processing four steps
The PCB board where the component is placed is placed into the machine from one end. On a double-track conveyor belt, the circuit board of the newly placed component passes through the hot and cold zones of the reflow furnace, precisely controlling the me
How to do electromagnetic compatibility design in PCB design and wiring?
How to do electromagnetic compatibility design :1. Suitable wire width,2. Key points of component wiring,3. Wiring rules for high frequency and high speed signals
