When does it make sense to rework a board instead of replacing it? A failed or malfunctioning PCB doesn’t always mean starting over. In most cases, what people call “circuit board repair” is really rework: targeted, component- or trace-level fixes…
What Is a Printed Circuit Board (PCB)? A printed circuit board (PCB) is a self-contained module that mechanically supports and electrically connects components using conductive copper pathways, “printed” onto an insulating substrate. Instead of loose wires running between components, a…
What Determines the Right PCB Material? The right PCB substrate material comes down to balancing three factors: the board’s thermal and electrical performance requirements, its operating environment, and cost. A material that’s overkill for a simple consumer product wastes budget,…
What Is PCB Inspection and Why Does It Matter? PCB assembly (PCBA) inspection is the process of verifying that a printed circuit board has been built correctly before it ships or advances to the next production stage. Key characteristics include:…
What Solder Mask Actually Does Solder mask is the thin polymer coating applied over a PCB’s copper traces, everywhere except the pads where components are soldered. It prevents unintended solder bridges, protects copper from oxidation and moisture, and is one…
What Is PCB Prototyping? PCB prototyping is the process of fabricating and assembling a small quantity, usually one to a few dozen units, of a new circuit board design to verify that it works before committing to larger production. It’s…
Should You Be Cleaning No-Clean Flux Residue? Here’s How to Decide If your boards have been assembled in the last couple of decades, they were almost certainly soldered with “no-clean” flux. It’s the industry default, including here at BESTProto. But…
BESTProto Quote Request Documentation Options If you’ve never worked with a contract manufacturer before, you might be wondering what project documentation to submit. The answer depends entirely on where your project sits in the development cycle. An early-stage concept with…
The Critical Bridge Between Concept and Mass Production Getting a hardware product from a promising design to a reliable, repeatable build is one of the most demanding challenges in product development. Most engineers and product designers who have been through…
When does your PCB prototype’s turnaround clock actually start? A quoted turnaround time doesn’t start counting down the day you place an order, it starts once everything BESTProto needs to begin building is actually in hand. Understanding that distinction is…
