Golden fingers are connected parts between the memory slot and the memory slot, and all the signals are transmitted through the golden finger. Golden fingers are composed of many golden -yellow conductive tactics. Because of its gold -plated and conductiv
The principle of high -frequency oscillator detecting metalAdjusting the gain potentiometer of the high -frequency oscillator just makes the oscillator be in a critical oscillating state, which means that the oscillator just vibrates. When the detection c
Golden finger classification1. Conventional gold finger (Qiping finger)Located on the edge of the plate neatly arranged the same length and width rectangular pad. It is often used in types of network cards and graphics cards. These gold fingers are more.2
Metal detector is a kind of instrument specially used to detect metal. It uses the principle of electromagnetic induction. The magnetic field produced can sensor the vortex current inside the metal. The vortex current will produce a magnetic field The det
What is Shen Jin PCB?Chemical nickel plating Shen (Enig or ENI/IAU), also known as Shen Jin (AU), chemical Ni/AU, or soft gold, is a metal electroplating process for manufacturing printing circuit board (PCB) to avoid Oxidation and improvement of copper t
PCB gold plating is simply the process of depositing gold onto the surface of the circuit board by electroplating. SMT placement has always been difficult as ICs and IC pins have become denser. Electroplating is an important stage in PCB production. Diffe
Characteristics of thick copper PCB: Thick copper PCB has the best elongation rate, which is not limited by processing temperature. The melting point is high, which can be used by hot-melt welding methods such as oxygen blowing and low temperature non-bri
