Low Temperature Solder Alloys and Their Behaviour A low temperature solder alloy melts well below the standard lead free range, which allows an assembly to be reflowed at a temperature that the components and the laminate can tolerate more easily. The benefit is real and the trade offs are equally…

PCB Conveyor Problems: 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 conveyor problems gives you a practical advantage when you…

PCB Conveyor Cost: What Matters on the Production Line 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 conveyor cost from the perspective of a PCBA factory floor,…

PCB Conveyor Checklist: A Practical Manufacturing Guide 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 conveyor checklist gives you a practical advantage when you choose…

PCB Conveyor Control: 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 conveyor control from the perspective of a PCBA factory floor, covering controlling…

Bow and Twist Measurement in PCB Panels Bow and twist are the two ways a panel loses its flatness, and they are measured differently, caused differently and corrected differently. They are grouped together in most specifications, which is a source of confusion when a lot is rejected and nobody is…

Silkscreen Legibility Rules for Densely Packed Boards Silkscreen is the part of a board that people read when something has gone wrong. A technician repairing a dense assembly needs to find R47 among a hundred passives, and the legend is what makes that possible. On tightly packed boards every millimetre…

PCB Conveyor Improvement: Practical Process Controls 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 conveyor improvement gives you a practical advantage when you choose a…

Kit Verification and BOM Accuracy A kit is the collection of material for one build, gathered before the build starts and verified against the bill of materials. Done well, it moves the verification away from the machine, where every mistake costs production time, to a bench where a discrepancy can…

Connector Placement and Retention Connectors are the components most likely to be damaged by handling and most likely to be blamed for a fault that occurred somewhere else. They are mechanically large relative to the joints that hold them, they are handled by the customer, and they are frequently the…
