End of Line Packing and Protection Packing is the last process before the product leaves the building, and it is the one that determines whether everything done before it arrives intact. A board that has been assembled, tested and coated can still be damaged by the wrong carton, a bag…

Work Order and Traveller Control A work order authorises a build, and the traveller that accompanies it records what happened. Between them they answer the questions that arise whenever something goes wrong: which revision was built, which material lots were used, which processes were applied and who verified each step.…

Maintenance Planning for Assembly Equipment Assembly equipment fails in two ways: suddenly, when a part breaks, and gradually, when a parameter drifts far enough to produce defects. Planned maintenance addresses both, and it is justified by the cost of the alternative rather than by a preference for order. An unplanned…

PCB Revision Control Data: What the Numbers Say 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 revision control data from the perspective of a PCBA factory floor,…

PCB Revision Control Specification: From Design to Repeatable Production 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…

Assembly Floor Layout and Flow How a floor is laid out decides how far a board travels between operations, how much work in progress accumulates beside each station and how quickly a problem at one machine becomes a problem for the whole line. Layout is often treated as a facility…
