Overcome the challenge of alignment of multiple connector groups between PCB boards
The procurement of certain PCB boards is controlled only by the specifications embedded in the Gerber packet. PCB boards can be built from these packets, regardless of mechanical tolerances.
What does impedance mean to PCB boards?
In a circuit with resistance, inductance, and capacitance, an obstacle to alternating current is called an impedance. Impedance is usually denoted by Z, which is a complex number.
Why should there be a test site when producing PCB boards
In the mass production factory, there is no way for you to use an electric meter to slowly measure the correct Circuit of every resistor, capacitor, inductance and even IC on each board. Therefore, the so-called ICT(in-circuit-test) automatic Test machine
PCB boards often peel off the original size Reasons
A typical manufacturer can only request it twice per production cycle, and only check it once every few months. IR testing in simulated batches also prevents more spills of defective products, which are a prerequisite for quality PCB factories. In additio
