How We Match High-Frequency PCB Materials to Circuit Requirements
High-frequency circuit performance depends on a complete interconnect: material, stack-up, copper, trace geometry, vias, launches, finish and assembly. We help…

How We Control PCB Stack-Up and Impedance in Manufacturing
A stack-up is the manufacturing definition behind routing, reference planes, impedance, thickness and many via structures. We review the customer's electrical…
How We Assemble Circuit Boards into Controlled PCBAs
PCB assembly is not simply placing parts on a board. The delivered PCBA depends on released data, authorized components, tooling, solder processes, inspection,…
How We Use Manufacturing Software to Reduce PCB and PCBA Risk
Software can compare geometry, generate machine data and connect records, but it does not decide which customer requirement is correct. We combine digital chec…
How We Review Rigid-Flex PCB Materials for Reliable Production
A rigid-flex PCB is a regional construction, not a rigid board with a flexible label. Rigid laminate, flexible dielectric, copper, coverlay, adhesives and stif…
What Bare Board Testing Evidence Can We Provide?
A bare PCB test report should answer a specific fabrication question and identify the lot and revision it represents. We separate electrical continuity and iso…
What We Need to Quote and Manufacture Your Heavy Copper PCB
“Heavy copper” is not enough information for a reliable quotation. Copper may be described as starting foil, finished thickness or a weight, and different laye…
How to Move a PCB Design Into an Accurate Manufacturing RFQ
An accurate PCB or PCBA quotation needs product files, construction, quantity, sourcing scope, inspection, testing and required evidence. If these inputs are m…
What Are Circuit Boards Made Of?
A printed circuit board is made from conductive copper, insulating dielectric materials, plated holes or vias, solder mask, surface finish and identification i…
PCB and PCBA Testing Methods: What Each One Proves
Select a PCB or PCBA test from the failure question you need to answer. Bare-board electrical testing checks connectivity before assembly; AOI and X-ray inspec…
