Basics of Solder Paste selection for PCB Assembly
INTRODUCTION Solder pastes are amorphous putty-like soldering materials used to solder surface-mounted components to the Printed Circuit Board. [1] The effect of solder paste on the PCB’s structural and functional integrity is the paramount factor to consider when deciding on selection of solder paste for application. Many factors which contribute towards the strength of the solder joint and its conduction efficiency need to be addressed as well. This is not just a discussion on what measures and precautions to take during PCB assembly and reflow, but also to put into question what a PCB design [2] engineer should consider ...
Can a metal core Printed Circuit Board from PNC solve your thermal challenges?
A metal core (MCPCB) is a PCB with an aluminum or copper sub straight laminated directly to the PCB. Metal core PCBs are becoming the go-to solution for small footprint, high power components such as ultra high brightness LEDs. The metal core in the PCB acts as integral heat dissipater, conducting heat away from components through the thermally conductive metal core to a remote heatsink. Although UHB LEDS applications are the most common use of MCPCBs, PNC has fabricated Metal Core PCBs for compact DC to DC converters, high power MOSFET and solid-state relay applications along side their standard ...

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 ...
