It is mainly because the thin welding paste is more likely to form a larger cavity, or the thickness gap of the weld is too small, leading to the volatiles of the welding machine more difficult to discharge through this "channel", so that the pr...
PCB light board shipment inspection items: 1, basic inspection, 2, electrical performance test report, 3, metallographic section analysis report, 4, impedance test
The most important steps in SMT patch processing are summarized as seven steps: first, graphic alignment, second, Angle of scraper and steel mesh, third, scraper force, fourth, printing speed, fifth, printing gap, sixth, separation speed of steel mesh and
Requirements on the minimum length of tape for SMT patch proofing materials: In the production process of SMT patch, materials are mainly packaged by pallets and tape braiding. Such packaging is convenient for taking materials from the SMT patch machine a
The cost is reflected in four aspects of assembly: 1, auxiliary materials: tin paste, tin strip, flux, UV glue, through the furnace fixture, 2, smt patch processing, 3, DIP plug-in after welding hours, 4, assembly test: test fixture, test equipment, test
In the through-hole PCBA assembly technique, the component is inserted into the drilled hole and a strong solder joint is formed by wave soldering. Usually, through - hole components are inserted manually
Polarity means that the positive and negative electrodes or first pins of a component are in the same direction as the positive and negative electrodes or first pins on the PCB(printed circuit board). If the component does not match the direction on the P
Ways to improve SMT machining efficiency: (1) Aim for fewer component changes, (2) Focus more on PCBA assembly, (3) You should know every step of the SMT process
Composition of PCB manufacturing production cost: The production cost of PCB products refers to the total of direct materials, direct labor, direct labor and other direct or indirect costs actually consumed in the production process
This paper introduces the inspection requirements of PCBA processed products: 1. Inspection requirements of PCBA processed products; 2. Quality requirements of component mounting process; 3
Shenzhen kingford is a PCBA processing manufacturer with more than 20 years of experience in PCBA processing. We have our own SMT processing plant, which can undertake mass SMT SMT processing services. Next, we will introduce what problems need to be cons
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,
