Something about PCB assembly process and what you should know

Within any simple electronic devices we used nowadays, there is a PCB (printed circuit board) drive it to run. The PCB is the core component of the electronic devices, whether it is a consume product such as battery charger, the communication equipment such as mobile phone, or transportation tool such as vehicle, even it is … Continued

Must knows to heavy copper PCB and it’s manufacturers

What is the heavy copper PCB Usually, when out-layers or inner-layers of any printed circuit board are specified to use ≥2oz base copper foil, we call it heavy copper PCB (or thick copper PCB board). For final finished copper thickness (means base copper + plating copper) we normally follow customers’ requirements to do.But,if no specific … Continued
