Electric soldering iron is the main repair tool. The core process of patch processing how to repair components is: diswelding and disassembling of chip components, cleaning of pad and assembly and welding of components.
Arrange professional PCBA production engineers to be responsible for SMT production line operation. Business, purchasing and production departments can cooperate with the review of new orders, production arrangement and product testing.
As the complexity of electronic circuits continues to increase, new technologies raise the bar for these products.
Teach you how to choose quality pcb manufacturers:First, look at the product, two, see the application, three, listen to the voice, four, see the reputation, five, see the service
How to improve the SMT patch processing quality?First, select technical personnel, second, ensure the accuracy of equipment, third, set up quality detection control points, fourth, improve the management system, five, formulate rules and regulations
The heat declared by the equipment must be removed by heating, ventilation and air conditioning equipment, which will require double power. In the welding is directly affixed to the surface of the printed circuit board, the electrode is welded to the same
We call PCBS single panel. Because a single panel has many strict restrictions on the design circuit (because there is only one side, the wiring can not cross and must go around a separate path)
Mobile terminal with HDI board is the main point of PCB growth. The mobile terminal represented by smart phone drives HDI board higher density and thinner. PCB all to high density fine line development, HDI board is particularly prominent.
Through the hole plug oil process is one of the hole treatment methods, the first is to opaque, above must have ink cover, plugging; The second is the hole can not appear yellow phenomenon, and do not touch tin.
After years of development, the PCB industry has also extensively upgraded its processes and capabilities. Some PCBS that were previously considered exotic will soon be considered routine.
The mechanical drilling technology used in PCB processing has been unable to meet the requirements, so a new microhole processing mode -- laser drilling has been developed rapidly.
The PCB industry has been shifting its focus to Asia, gradually forming a new pattern with Asia as the center and other regions as the auxiliary. The Asian continent has become the main production base of PCB and its high-end products HDI in the world.
