HDI Printed Circuit Board
HDI boards, another of the highest technology in PCBs, also are accessible at Incredible. HDI Panels have blind and hidden visas and typically include MicroVAX of .006mm or below in size. They feature a greater circuit complexity than ordinary circuit boards. What is HDI PCB? HDI stands for High-Density Interconnector. Any SATA connector with a greater wire volume per square meter than a regular board is termed HDI circuit board. HDI PCBs feature narrower gaps and outlines, more minor visa and grab pads, and increased connecting pad frequency. It is beneficial in boosting electrochemical characteristics and lowering the shape and volume of ...
PCB assembly Pre-Reflow FAI
First article inspection (FAI) prior to SMT assembly [1] is a design verification methodology that provides a reported verification and validation of details of a product on the shopfloor per its manufacturing procedure and requirements. There are various ways to perform FAI, from both supplier’s and customer’s side, making it a very dynamic process. This means that each organization can tailor its FAI method to benefit itself and consequently, its customer, yet maintain rigid performance standards at the same time. FAI involves qualitative and quantitative measurement. FAI is also highly effective since it can potentially fulfill process validation requirements of ...
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 ...
Printed Circuit Board thickness considerations and requirements
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 ...
Ensuring a successful Turnkey PCB Assembly project
There are many detailed factors involved when pursuing the right company for your electronic or PCB assembly [1] needs. These factors can be broken down into two distinct areas, customer communication and supplier contract review. Either the customer or the supplier cannot afford time lost if there is a misunderstanding or lack of data to efficiently and effectively produce a quality product on time. Time spent up front makes for a smooth and efficient transition through the quoting and manufacturing process. Customer communication A majority of communications for a request for quote, RFQ’s, in today’s industry are via email. The email needs ...
