How to OEM request PCB assembly quotes (RFQ) for EMS manufacturing

By Staff

PCB_Assembly_ServicesYour current contract electronics provider just missed a shipment to one of your important customers because of ongoing, internal EMS systems test yield issues. You indicated this recent quarter was important and they promised you your delivery schedule would be met. You suggested the current EMS provider and now your company’s reputation, and possibly your career, is on the line.

You now have to revisit your request-for-quote process and prepare RFQ letters for your program’s BOM, PCB assembly and box build and look for alternative EMS provider services.

[Dear EMS Provider]

[OEM] latest product line, code named “Davos,” was initially released in [date]. It has been received with tremendous interest and orders from top investment firms, hospitals, and the U.S. government. Now, with our design stabilized, and the shipments increasing 35% to 50% quarter-on-quarter, we are looking into positioning our product to meet our future demands, pricing needs, quality level, and supply chain management abilities. In our planning discussions, we have identified [EMS Provider] as a potential candidate for moving forward with our growing production needs.

Our product is currently sourced with an electronics manufacturer that is not positioned ideally to support our strategic direction. This quote package is not the full product offering, but representative of the business that potentially could be awarded.

Our intent with this package is to validate the business assumptions on our strategic direction and select the suppliers to discuss our comprehensive agreement.
