PCB Layout vs PCB Design Service: What Is the Difference? Two Overlapping Services PCB layout and PCB design are often used interchangeably, but they describe different amounts of work. Layout takes an existing circuit and turns it into a manufacturable board. Design starts earlier and includes deciding what the circuit…

PCB Laminate Water Absorption Test: Soaking the Board 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 laminate water absorption test gives you a practical advantage…

Aluminum PCB Materials: Base, Dielectric and Copper Foil What an Aluminum PCB Is An aluminum PCB is a metal core board, usually built as an insulated metal substrate. It has three functional layers: an aluminum base plate, a thin dielectric layer, and the copper foil that forms the circuit. The…

SMT Stencil Alignment: Lining the Stencil to the Board Modern electronics depend on boards that are assembled correctly the first time. Every product – a phone, a charger, a medical instrument or an industrial controller – relies on thousands of solder joints that must conduct current for years. This article…

High Temperature PCB Manufacturing: Materials to Finished Test What Counts as High Temperature A high temperature board is not defined by a single number, because the laminate has several thresholds that matter at different points in its life. The glass transition temperature, Tg, is where the resin softens and the…

PCB Copper Trace Crosstalk: Signal Leaking to a Neighbor 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 copper trace crosstalk from the perspective of a PCBA factory…

Drone Mainboard vs Flight Controller PCB: What Is the Difference? Two Boards with Very Different Jobs In a drone the electronics are usually split between a flight controller and a mainboard, and the two are designed with opposite priorities. The flight controller exists to keep the aircraft stable, which means…

SMT Reflow Solder Joint Porosity: The Pores in the Solder 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 SMT reflow solder joint porosity gives you a…

PCB Assembly vs Box Build: What Is the Difference? Two Levels of Service PCB assembly and box build are often quoted together, but they describe different scopes of work. PCB assembly produces a populated circuit board. Box build takes that board, or several of them, and turns it into a…

PCB Surface Finish Tin: A Simple Tin Finish 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 surface finish tin from the perspective of a PCBA factory floor,…
