PCB Bill of Materials Control: Holding It Steady 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 bill of materials control gives you a practical advantage…

PCB Bill of Materials Improvement: Getting Better Each Lot 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 bill of materials improvement gives you a practical…

PCB Bill of Materials Environment: Where It Happens 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 bill of materials environment gives you a practical advantage…

PCB Bill of Materials Traceability: Following One Board 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 bill of materials traceability gives you a practical advantage…

Assembly Pallet and Fixture Design for SMT Production A pallet is the carrier that holds a board through the assembly line, and a well designed one is invisible: the board sits flat, the fiducials are visible, the conveyor grips it and nothing moves. A badly designed one produces placement errors,…

Board Cleaning After Reflow in Mixed Assembly Lines Board cleaning after reflow is a line integration problem as much as a chemistry problem. The cleaner has to sit between the reflow oven and the next operation, accept the same panel size and throughput, and deliver a dry board at the…

PCB Bill of Materials 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 bill of materials specification gives you a practical…

PCB Bill of Materials Handover: Passing It On 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 Bill of Materials Timing: How Long It Takes 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 bill of materials timing from the perspective of a PCBA…

Photoresist Selection for Inner Layer Imaging Guide On an inner layer the photoresist is the stencil for the etch, and its properties decide the finest line the shop can hold and the defect rate it can live with. Choosing a resist is therefore a matter of matching its resolution, its…
