Why is PCB automatic routing not accepted by engineers?
Although PCB automators have been around as long as engineers have known about CAD, engineers involved in designing dense boards have almost completely ignored the implementation of automated technology.
PCBA process control and quality control of 6 key points
PCB manufacturing process involves circuit board manufacturing, component procurement and inspection, patch processing, plug-in processing, program firing, testing, aging and a series of processes.
Common welding defects and prevention in reflow welding
Due to the improper operation in the printing process and mounting process, the parameter setting of reflow welding is not reasonable, and many common welding defects will appear.
What is the shelf life of PCB? And how about the baking time and temperature?
After the manufacturing of PCB circuit boards, there is a shelf life, beyond which the PCB needs to be baked, otherwise it is easy to cause the problem of PCB board bursting when the SMT is put on line for production.
Four PCbas track the pros and cons of barcode printing
Many companies use tracking barcodes to allow the plant's field information management system to track the quality of PCBS produced. From the original label paper printed bar codes to today's laser printed bar codes can achieve this purpose.
What are the general requirements of PCBA outsourcing processing?
During the industry boom, many PCB processing manufacturers will carry out PCBA outsourcing processing under the condition that they cannot normally schedule production. Send PCBA orders to other competent PCBA manufacturers.
Why is the acquisition of electronic materials so lucrative? What are the risks?
Now there are many companies or individuals that recycle electronic materials. They use various channels to recycle these electronic materials in the market, although the recycling of electronic materials is a good way to save social resources.
PCB board substrate material classification
There are many kinds of PCB substrates, but they are generally divided into two categories, namely inorganic substrate materials and organic substrate materials.
Advantages and disadvantages of SMT
The smaller size of SMT compared to traditional through-hole inserts makes manual repair at mount or component level more difficult, requiring skilled workers and more expensive repair tools.
In-depth interpretation of SMT technology
SMT is an electronic circuit production technology where components are mounted or placed directly on the surface of a printed circuit board. In this industry, there are two methods: SMD and THT.
The four major factors of achieving the goal of high reliable quality
Set up relatively complete electrical equipment process specifications, including specifications for PCB circuit design and manufacturing specifications, establish the corporate culture of manufacturability design.
