SUPREME CIRCUITS is a company that offers a variety of printed circuit board (PCB) services. They specialize in non-plated through-hole (PTH) single- and double-sided PCBs, as well as double-sided and multi-layer PCBs (ML). Additionally, they provide prototyping services for those looking to test out their designs before full production. Printed circuit boards are essential components in electronic devices as they provide a platform for connecting different electronic components and enabling the flow of electrical signals. The quality and design of the PCB can significantly impact the performance and reliability of the overall electronic system. One of the key services offered by SUPREME CIRCUITS is non-plated through-hole (PTH) single- and double-sided PCBs. These types of PCBs do not have plated through-holes, which are small copper-lined holes that connect different layers of the board. Non-PTH PCBs are typically less expensive and easier to manufacture compared to PTH PCBs. They are suitable for simpler electronic designs that do not require complex routing of signals. In addition to non-PTH PCBs, SUPREME CIRCUITS also provides double-sided PCBs.
