Automotive Radar PCB: Materials for 77 GHz Designs An automotive radar module works at 24, 77 or 79 GHz, and at those frequencies the circuit board stops being a passive carrier and becomes part of the radio. Trace geometry, dielectric behaviour and copper surface finish all change the insertion loss…

PCB Flex Bend Radius Rules: From Design to Repeatable Production Electronics manufacturing has become a discipline of small details. Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB flex bend radius rules from the perspective of a…

PCB Flex Stiffener Attachment: A Practical Manufacturing Guide Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB flex stiffener attachment gives you a practical advantage when…

Designing a Microwave Transmitter PCB for Continuous Duty A microwave transmitter runs hot, runs continuously and cannot tolerate a small error in the wrong place. At several gigahertz a fraction of a decibel of extra loss reduces the link margin, a few degrees of phase drift spoils a phased array,…

PCB Marking on A Flex Circuit: Process Details and Inspection Points Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB marking on a flex circuit gives…
