Solder Preform: Design Rules and Process Limits A solder preform is a shaped piece of alloy that is placed at the joint and melted in a reflow pass, so the alloy volume is set by the piece rather than by the printing process. That single property is why preforms appear…

PCB Shop Humidity Timing: How Long It Takes 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 shop humidity timing gives you a practical advantage when…

Soldering Iron Tip Temperature Verification A soldering station displays a number that is not the temperature of the joint. The sensor sits in the heater or in the tip cartridge, the display is calibrated to that sensor, and the interface between the tip and the work adds its own thermal…

Jet Dispensing for Solder Paste in Small Batch Production Jet dispensing writes solder paste one dot at a time from a nozzle, without a stencil, without a squeegee and without a printing stroke. For small batches, for awkward board shapes and for assemblies where deposits of different heights are needed,…

Electrostatic Discharge Safe Packaging for PCB Shipment An assembled board that leaves the factory in the wrong packaging can arrive electrically damaged without a single mark on it. Electrostatic discharge damage to finished assemblies is usually latent, appearing as leakage or as a marginal input threshold rather than an obvious…

PCB Shop Humidity Plan: Laying It Out First 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 shop humidity plan gives you a practical advantage when…

PCB Shop Humidity Handover: Passing It On 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 shop humidity handover gives you a practical advantage when you…

PCB Shop Humidity Environment: Where It Happens 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 shop humidity environment from the perspective of a PCBA factory floor, covering…

PCB Shop Humidity Specification: Writing It Down Precisely 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 shop humidity specification gives you a practical advantage when…

PCB Shop Humidity Standards: Agreeing the Rules 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 shop humidity standards from the perspective of a PCBA factory floor, covering…
