printed circuit board testingWhen it comes to custom testing solutions for the electronic test industry, one of the areas that we deal with the most is printed circuit board testing. Printed circuit boards or PCBs are used in many different types of electronic and electric products. The printed circuit board testing is a custom functional test that is designed to ensure that the PCB is working as it should. At EMC Technologies, we design and manufacture printed circuit boards to support mechanically and also connect electrically all of the various electronic components through the use of conductive tracks, pads, and other features. Etched from sheet layers of copper and laminated onto or in between layers of a non-conductive substrate, the components are typically soldered onto the PCB according to the requirements of the project.

Custom Testing Solutions

At EMC Technologies, we provide top quality custom solutions for our clients who come to us from many different and diverse industries. We work closely with each client at the development phase to ensure that everything from interface test adapters to custom functional test fixtures is designed to accommodate their unique requirements. We work with a wide variety of products and services, including custom wiring, RF circuit assemblies, and custom interface test adapters. The designs that we develop come from our team of highly trained and skilled engineers and technicians; however, we provide a single point of contact for our customers to help streamline the process.

The designs for PCBs can be very basic, ranging from a very simple double-sided design to something more complex, such as a multi-layer design. We provide design, development, manufacturing, and printed circuit board testing at EMC Technologies because we understand the importance of this aspect of each project. We use PCBs in our designs because they provide a greater signal integrity that is needed to provide our clients with reliable and repeatable results. Our diligence pays off, as it helps to reduce debugging time, troubleshooting, and provides us with the ability to create faster and less expensive exact duplicates of the interface test adapters for our customers.

Printed Circuit Board Testing

Once we have manufactured, assembled, and populated the PCBs at our facility, we can then provide testing for quality assurance. Depending on the project, there are a few different ways that PCBs can be effectively tested. An automated optical inspection or visual inspection is typically performed with the power off to maintain quality control in PCB manufacturing. Another type of printed circuit board testing is with the power on, which is when we use an in-circuit test to perform physical measurements, such as voltage. Power off testing can be performed using an analog signature analysis for additional testing. All of these tests work to ensure that the custom wiring was assembled and appropriately populated. In addition, other custom functional test options and custom testing solutions can be conducted to make sure the PCB does what it was designed to do.

To provide for accurate printed circuit board testing, additional pads are often added to the PCBs for the purpose of using temporary connections. This allows us to perform an in-circuit test to check on certain features of some components using what is known as a boundary scan test. We can also use this method to program the non-volatile memory components onto the PCB. The great thing about printed circuit boards is that if they fail in any way, our technicians can desolder and replace any parts that have failed. We offer a wide range of services for PCB design, manufacturing, and printed circuit board testing. Some of those services include contract manufacturing and electro-mechanical assembly, custom wiring solutions, and built-to-print test adapters for commercial products.
