Editor Stephen Las Marias spoke with Russell Poppe, manager of technology, on the issues of coping with flexible circuit assemblies and provides methods to tackle them.
Stephen Las Marias: From your experience, what are the primary complications in flexible circuit assembly?
Russell Poppe: From an assembly angle, baking the flexible circuits just before manufacturing assembly is very important as they can be susceptible to delamination. Having said that, baking any Electronic Board prior to manufacturing is best practice and something we usually carry out at JJS.
One of the primary complications in flexible circuit assembly is to ensure the circuits remain flat, in particular throughout the printing and pick-and-place processes. The components of the circuit needing SMT placement ought to have an FR-4 stiffener designed in underneath; but it’s also essential to work with the Electronic Board supplier up front. Getting the panelization right is critical so that the boards don’t bend when the components are placed or when they pass through reflow. Panel design is often a headache as flexible circuits are generally odd shapes! It may additionally be necessary to have a tailored carrier or pallet to hold the flexible circuits in place during the entire process; having said that, these carry increased costs-typically several hundred pounds each.
