What is the 01005 process? Why is 01005 process expensive in PCBA processing?
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...
The effect of welding method on tin penetration of PCBA was analyzed
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
How does PCBA proofing reduce casting rate
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
PCBA processing reflow welding and wave welding difference
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
Causes of virtual welding in PCBA processing
The reasons for the appearance of virtual welding in PCBA processing are as follows: 1. Oxidation of pad and component pins; 2. Less tin; 3. The temperature is too high or too low, 4 welding paste melting point is low, 5, solder paste quality problems
PCBA processing workshop environment and personnel requirements
PCBA processing on the workshop environment specific requirements: one, temperature, humidity requirements, two, ventilation capacity, three, power requirements, four, electrostatic protection requirements

PCBA processing technology of the four links
The process process of PCBA can be roughly divided into four main links: SMT patch processing →DIP plug-in processing →PCBA testing → finished product assembly
PCBA processing process
According to the welding pad surface treatment classification: organic weldability protection layer (OSP), nickel metal leaching (ENIG), nickel palladium leaching (ENEPIG), silver Immersion silver, tin immersion.
