Bare Board Printed Circuit Boards

A bare board PCB (printed circuit boards) and the bare board testing play critical roles in PCB creation. Bare board, is the PCB before the electric components or through holes are placed on it. A bare board printed circuit boards 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 can configure PCB bare boards as per your specifications while also offering effective bare PCB testing capabilities. Technotronix is a leading bare board provider in California, United States. We can manufacture configurations of bare circuit boards based on your custom specification.

Our bare printed circuit boards also assist you in penalization, place your PCB on large boards, mounting and plating process. We understand the complexity of PCB bare board manufacturing. Our goal is to provide best product which can fit your needs and best customer service.

Capabilities of Bare Circuit Boards

Technotronix Inc is known for its ability to offer high quality PCB bare boards. Our capabilities include designing bare boards to your bespoke needs to that they can support the components that you require.

In addition, our bare board (PCB) also help you in panelization as well as placing your Printed circuit board to larger boards.

Continuity Testing: Which involves verifying there are no open points within the circuit.

Benefits of PCB Bare Board

Bare Circuit Boards come with a number of advantages including:

  • Saving on Costs - This stand to reason since you are undertaking extensive testing in the initial stages of the design. What you do not have to contend with, therefore are Bare printed circuit boards that are wrongly assembled, which can turn out to be a very costly mistake.
  • Saving on time - Once again, since you are identifying issues in the early 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 the reliability that it offers. At a time of miniaturization, boards are extremely densely populated. It is, therefore, important to ensure that your bare board (PCB) is up to soldering the expensive components on it.
  • Our bare board testing is done vide the Flying Probe Method that works well even for small production volumes and offers affordability as well as flexibility.

Application of Bare Boards (Printed Circuit Boards)

  • High quality PCBs find applications across industries from consumer electronics to industrial applications, medical devices, automotive application & more.
  • Bare board PCB testing also finds ubiquitous use as it can improve the PCB design process.
  • It is extremely helpful in early stages of development as it streamlines many aspects of production, besides leading to savings in cost & time.
  • With Printed circuit boards, being smaller and densely populated, its importance is only slated to grow as it is getting more and more challenging to keep track of the traces, vias, through holes and more.
  • With bare boards, you tend to save time and money on costly errors, repairs and maintenance.
