PCB bare board 4L Black Soldermask buried Hole PCB manufacturer | YMS PCB

Short Description:

As the name suggests, bare boards are printed circuit boards (PCBs) without the functional components, including the circuitry and through-holes. These boards consist of only a substrate, metal coating, and conductive pathway, forming the foundation for the future PCB manufacturer.
Bare boards are designed to be configured, so they can be used to test design, concept, and functionality before more expensive components are assembled. Because of this, bare boards offer a lot of benefits in cost and time savings, early defect detection, time-to-market for a competitive edge.

Printed Circuit Board Introduction

A printed circuit board (PCB) mechanically supports and electrically connects electrical or electronic components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it.PCBs can be single-sided (one copper layer), double-sided (two copper layers on both sides of one substrate layer), or multi-layer (outer and inner layers of copper, alternating with layers of substrate). Multi-layer PCBs allow for much higher component density, because circuit traces on the inner layers would otherwise take up surface space between components. The rise in popularity of multilayer PCBs with more than two, and especially with more than four, copper planes was concurrent with the adoption of surface mount technology.
