Although PCB can be called a high-tech product in the electronics industry, but now the development of PCB is not only challenged by its own cost-effectiveness problems, more is from the challenge of energy conservation and environmental protection.
The reason for the high price of SMT proofing in small batches: The proofing cost of small batches of SMT mainly includes start-up fee, engineering fee, steel mesh fee, processing fee calculated according to conventional points, or summarized directly wit
Circuit board is the necessary material of PCBA processing plant, circuit board is mainly to provide a carrier for various electronic components, and components link together to form a complete circuit.
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.
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.
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.
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.
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.
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.
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.
There are many kinds of PCB substrates, but they are generally divided into two categories, namely inorganic substrate materials and organic substrate materials.
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.
