There are many copper welding methods, and there are differences in welding methods for different copper products. Commonly used methods include : Gas welding Manual carbon arc welding Manual arc welding Automatic welding can also be used for large structures. Now we use red copper and brass as examples to briefly explain the differences between the above 3 welding methods,…

What is Controlled Impedance? Unless you have carefully designed the trace and its environment, impedance is typically “uncontrolled”, meaning that impedance will vary in value from point to point along the trace. At high frequencies, PCB traces do not behave like simple connections, controlled impedance helps us ensure that signals are not degraded as they…
What is a PCB assembler? Printed circuit board assembly is the process of connecting the electronic components with the wirings of printed circuit boards. The traces or conductive pathways engraved in the laminated copper sheets of PCBs are used within a non-conductive substrate in order to form the assembly when a large number of PCBs are required, the components aren’t…
What is the impedance control or a controlled impedance? Impedance is the result of the interaction between the resistance and reactance in a circuit and expressed in Ohms. Impedance is an AC characteristic, which means it is related to frequency. A controlled impedance is important to maintain signal integrity, especially for high-frequency products. INQUIRY NOW…
Thick Copper PCB Definition Thick Copper PCBs are printed circuit boards with 3 or more ounces of finished copper in the inner or outer layers The additional copper PCB thickness enables the board to conduct a higher current, achieve good thermal distribution and implement complex switches in a limited space. Other advantages include increased mechanical strength…
