PRINTED CIRCUIT ASSEMBLY TESTING
No single printed circuit assembly [1] testing system will meet all the requirements of every manufacturing environment. PNC employees the three most commonly used testing methods for defect detection being Functional Test (FCT), In circuit Testing (ICT) and Flying probe testing. Each test method will have different results based on your test strategy. Your testing strategy must be developed with consideration to many factors such as reliability, cost or functionality traits. The key here is to detect defective boards and catch issues prior to end usage. Some considerations like opens, shorts, resistance, capacitance, inductance, diode issues, detecting incorrect component values, ...

CONFORMAL COATING
What is Conformal Coating? Conformal coating is protective chemical material coating applied after the final SMT PCB assembly [1] or through-hole assembly process. Coatings are comprised of 5 different types, Acrylic, Epoxy, Urethane, Silicone and Parylene resins. Applying the coatings to a PCB board assembly [2]can be done by hand spray, robotic spray, brush or dipping. The coating acts as an additional dielectric layer that provides protection due to environmental and mechanical stresses, such as thermal extremes, chemicals, dust, salt fog, abrasions, and moisture. In a PCB assembly [3] that has close spacing of conductive pathways or close ...
Let PNC Simplify Your Printed Circuit Board Design With, CPLDs
New product designs continue to get more compact, while the performance and the number of features that customers expect continue to increase. To the engineer, this means higher PCB circuit densities and less room on the PCB for just-in-case design, such as unallocated I/O, or 0 ohm resistor networks to allow for reconfiguration of the PCBs at PCB assembly [1]. Meanwhile, new product prototype cycles are also getting faster. 3D printed mechanical parts are available within hours, putting pressure on electrical engineers to work faster and get their PCB designs [2] right the first time. Even the fastest PCB fabrication, such ...

How Do You Select a Printed Circuit Board Thickness? Selecting the correct PC Board [1] thickness for your product requires balancing of three often competing aspects of the design: manufacturability, electrical performance and mechanical constraints. Modern PCB fabrication techniques at PNC give the PCB designer great flexibility in specifying the PCB lamination stack-up and gives them the option to design a PCB in a thickness other than the typical choices of .031”, 062” or .093”. Manufacturing considerations in selecting a PCB thickness To understand how to specify PCB thickness, it is important to understand how PCBs are fabricated. Most multilayer PCBS from 2 ...
