Bare Board Printed Circuit Boards
A bare board PCB and the bare board testing play critical roles in PCB manufacturing. A Bare board is the PCB before the electric components or through holes are placed on it. A bare board PCBs are comprising of:
- Substrate
- Metal Coating
- Conductive Pathways
Through a bare board layout, you could determine the placement of the components. In addition, the bare board testing can go a long way in ensuring that what you have is a reliable product.
At Technotronix, we configure bare PCB boards as per your specifications while also offering effective bare PCB testing capabilities.
Our bare printed circuit boards also assist you in penalization, placing PCB on large boards, mounting and plating process. We understand the complexity of bare board PCB manufacturing and provide the best product which can fit your needs.

BARE PCB BOARDS BENEFITS
- Saving on Costs - This stands to be a reason since you are undertaking extensive testing in the initial stage of design. Therefore, it helps in preventing the repair and maintenance costs of the PCB bare boards.
- Saving on time - Once again, since you are identifying issues in the initial stages, you don’t tend to lose out on precious time. This can be a huge source of competitive advantage, since this could mean quick time-to-market.
- Easy Resolution - With bare board testing it will be easy to identify and resolve issues early on.
- Reliability - The most important advantage of bare board testing is its reliability. At a time of miniaturization, boards are extremely densely populated. Therefore, it is important to ensure that your bare boards are up to soldering the expensive components on it.
- Our bare board testing is done via the Flying Probe Method that works well even for small production volumes and offers affordability as well as flexibility.
APPLICATION
- Consumer electronics
- Medical
- Automotive
- Telecommunication
- Aerospace
- Renewable Energy and more.
