Sanmina’s ability to manufacture the PCB, fabricate the metal enclosure, assemble the PCBA, build and test the complete system simplifies prototype and accelerates time to market.

A leading multimedia OEM needed a complex metal enclosure produced in 2.5 weeks. Sanmina provided DFM recommendations, modified turret tools, developed pancake tools and fabricated the enclosure in 2 weeks.

Sanmina delivered a complex networking PCBA within 72 hours. The board had multiple BGAs, a long form factor (28” x 14”) and required an OSP surface finish.
