While designers place components and route circuits on multiple layers, manufacturers have to fuse the disparate layers of the board into a single, continuous product. High heat and pressure cause board laminate material to flow throughout the crevices of the design and encapsulate the board shape; this process is reversible (sometimes destructively so) under certain…
Printed circuit board designers must communicate the manufacturing intentions of a project so that there aren’t any problems in building the board. To do that, consider all ways to ensure that data in PCB design documentation is as straightforward as possible. In the layout, designers must balance the circuit’s optimal needs against the board’s constraints…
IEC 62474 is an international industry standard that facilitates transferring and organizing material declaration data between businesses.
Managing supplier materials for electronics manufacturing can be challenging. Poor, incomplete, or absent material declarations can become significant roadblocks when sourcing compliant sub-products and components. Research and correspondence with suppliers can be slow-moving at times, and time is of the essence for designers on tight production schedules. The industry standard IPC-1752A helps to coordinate efforts between the disparate chemical, material, and sub-product manufacturers integral to PCBA production.
It’s important that PCB designers clearly communicate the manufacturing intentions of a project. Here are some ways to ensure the data in your PCB design documentation is as clear as possible.
Simulation is necessary to gauge system response and model performance when designing PCBs for manufacturing. However, real-world imperfections in manufacturing processes mean that component values differ from their nominal values; how much they differ depends on how tight the tolerancing is. Component tolerance is a vital aspect of board cost and performance as per-unit prices…
