PCB Tooling Charge Review: A Second Look 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 explains PCB…

Tented Via: 5 Rules for Mask Coverage A tented via is a via whose opening is covered by solder mask, so the hole and its annular ring are sealed under the coating instead of being left open. The purpose is simple. An open via next to a pad can wick…

PCB Tooling Charge Plan: Laying It Out First 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 tooling charge plan from the perspective of a PCBA factory floor,…

PCB Tooling Charge Data: What the Numbers Say 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 tooling charge data gives you a practical advantage when…

PCB Expedite Audit: Checking the Practice 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 expedite audit gives you a practical advantage when you choose a…

Step Board: 5 Rules for Cavity Depth Control A step board is a printed circuit board with a pocket milled into it so that a tall component can sit below the surface of the panel. The pocket, usually called a cavity, is created by controlled routing depth, and it lets…

PCB Expedite Cost: What It Adds Up To 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 explains…

PCB Expedite Problems: When It Goes Wrong 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 expedite problems from the perspective of a PCBA factory floor, covering troubleshooting…

Stacked Via: 5 Rules for HDI Reliability A stacked via is a microvia placed directly on top of another microvia, so the connection passes through two or more HDI layers without a landing pad between them. The arrangement saves the space that an offset or staggered build would need, which…

PCB Expedite Checklist: What to 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 article explains PCB expedite…
