PCB Drill Environment: A Practical Manufacturing Guide 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 drill environment from the perspective of a PCBA factory floor, covering controlling…

Controlling Environmental Conditions in PCB Production Environmental conditions are the background of every process in a board shop, and they are usually noticed only when they change. A room that is too dry generates static, one that is too humid slows the drying of resist and affects the exposure, and…

Moisture Control in PCB Production Moisture is present in every board shop and in every material the shop handles, and controlling it is a matter of knowing where it causes harm. Absorbed moisture in prepreg expands violently during lamination, moisture in a package turns to steam during reflow, and moisture…

PCB Drill Traceability: Design and Assembly Considerations 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…

PCB Drill Timing: A Practical Review for Manufacturing Teams 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 drill timing gives you a practical advantage when…

PCB Drill Handover: Process Details and Inspection Points 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 drill handover from the perspective of a PCBA factory floor, covering…

PCB Drill Improvement: Process Details and Inspection Points 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 drill improvement from the perspective of a PCBA factory floor, covering…

Reflow Profile Choice: Soak Versus Spike in SMT Assembly Every solder joint on a board is formed by a machine that knows nothing about the parts it is joining. It follows a thermal profile: a sequence of heating rates, plateaus and peaks selected for one combination of paste, components and…

ESD Safe Workstation Design for PCB Assembly An esd safe workstation is a small system rather than a bench with a mat on it. The surface, the operator connection, the floor, the tools and the packaging all have to be at the same potential and all have to be able…

Etch Factor Control In PCB Fabrication The etch factor describes the shape of the copper that remains after a trace has been etched. A perfect etch would leave a rectangular cross section with vertical walls; a real etch leaves a trapezoid, because the etchant attacks the sides of the trace…
