Support Pin: 5 Rules for Board Support in Printing A support pin is one of the small posts that hold the panel flat on the printer table while the stencil printing stroke runs across the top. Support is easy to overlook because it is invisible in the finished product, yet…

PCB Prototype Build Data: From Prototype to Volume Production 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 prototype build data gives you a practical advantage…

PCB Prototype Build Limits: From Prototype to Volume Production 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…

Foam Flux: 5 Rules for Uniform Wave Soldering A foam flux is the layer of flux that a wave solder machine applies to the underside of the board before it reaches the wave. Air is pumped through a porous stone in the flux reservoir, the flux becomes a foam, and…

PCB Prototype Build Maintenance: Key Process and Quality Checks 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 prototype build maintenance gives you a practical advantage…

PCB Prototype Build Setup: Getting Ready 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 prototype build setup gives you a practical advantage when you choose…

Excess Solder: 5 Rules for Fillet Size Control Excess solder is a joint that carries more alloy than the design intended, and it shows as a fillet that bulges above the pad or that swallows the lead. It is rarely called out on a drawing, yet it causes real problems.…

PCB Prototype Build Defects: What Goes Wrong Prototype runs expose problems that a mature product hides. The batch is small, the process is new, and every decision is made quickly. Most defects in a prototype build trace back to a few stages: data review, paste printing, placement, reflow and test.…

Solder Splash: 5 Rules to Stop Stray Solder A solder splash is any stray alloy that lands on the board surface instead of inside the joint. It appears as small balls, flat beads or fine droplets scattered around a footprint, and it is one of the defects that assembly houses…

PCB Prototype Build Standards: What Buyers and Engineers Should Check 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…
