Printed circuit board testing should be considered during all phases of production including design/layout, fabrication and assembly. Whether it’s a simple bare PCB board for continuity and netlist testing or functional test of an assembled board, tests are always strongly recommended. We offer a wide variety of PCB testing and inspections for all boards we […]
As PCB signal switching speeds increase today’s PCB designer needs to understand and control the impedance of PCB traces. With the short signal transition times and high clock rates of modern digital circuitry, PCB traces need to be considered not as simple connections but as transmission lines. This simple introduction is aimed at lines running […]
With the requirement of PCB heat dissipation capacity for high intensive electronic components and high-power electronic components, the industry has introduced embedded copper coin PCB technology. Using the high thermal conductivity of copper coin, the heat generated by the parts in the PCB is transferred to copper coin quickly, and then the heat is dispersed in the […]
With the development of electronic products and applications of finer pitch devices, vias play an important role in the interconnection between layers in a PCB, there are three main types of vias: through hole vias, blind vias and buried vias, each of them have different attributes and functions contributing to the overall optimal performance of circuit […]
The backdrill process removes stubs from plated-through-holes (vias). Stubs are the unnecessary / unused portions of vias, which extend further than the last connected inner layer. Stubs can lead to reflections, as well as disturbances of capacity, inductivity and impedance. This discontinuity errors become critical with increasing propagation speed. Backplanes and thick Printed Circuit Boards in particular, can endure significant signal integrity […]
A PCB surface finish is crucial for a printed circuit board as it prevents the copper (exposed traces, pads, holes and ground plains) from oxidation – a critical ingredient to high-level application performance. A surface finish is essential for making a reliable connection between the PCB and the electronic component. A surface finish has two major functions, to provide […]
Printed Circuit Board Tolerances FOR FABRICATION & ASSEMBLY Have you ever submitted a Gerber file only to have a laundry list of feedback and red-pen markup sent back to you, creating hours of revisions and delays for the engineering team? Delays like these not only increase the lead time of your product but increase costs, […]
