The advantage of high-frequency/microwave/radio frequency PCB board immersion gold process is that the color deposited on the surface is very stable, the brightness is very good, the coating is very flat, and the solderability is very good when printing circuits. The thickness of gold in high-frequency microwave radio frequency PCB board immersion gold is generally…

1.Direct replacement Direct replacement means directly replacing the original IC with other ICs without any modification, and the replacement does not affect the main performance and indicators of the machine. The replacement principle is: the functions, performance indicators, packaging form, pin usage, pin number and interval of the replacement IC are the same. The same…
