Considering Contract Manufacturing for Your PCB Assembly

If you’re transitioning from hand-building SMT prototypes to having your small boards assembled by a contract manufacturer, there are some key considerations to keep in mind. One important factor to think about is the placement of 9mm pots that protrude through a front panel, alongside the majority of SMT devices on the board.

When working with a contract assembler, you may opt to have them fit all the SMT parts and leave the placement of the 9mm pots to yourself for precise mechanical alignment. You might wonder if including a moderate number of no-fit conventional parts (up to 20) on the BOM provided to the assembler would pose any issues. In theory, this arrangement should not be a problem for the assembler.

Another aspect to consider is the placement of SMT devices in relation to the pots on the PCB. You might contemplate whether it’s better to have them on the same side as the pots or on the opposite side. Opting for the latter could potentially provide easier access to the SMT parts for any necessary rework in the future.

As you navigate this process, seeking advice and insights from experienced professionals in PCB fabrication and assembly can be invaluable. Making informed decisions at this stage can contribute to the successful production of your boards. Good luck with your PCB assembly project!
