SigmaTron’s Acuña, Mexico Facility Expanding SMT

Reading time ( words)

SigmaTron International’s facility in Acuña, Mexico added an SMT line last year and has placed an order for an additional line scheduled to arrive this summer.

“Our business grew significantly once Mexico eased its COVID-19 restrictions last April. That drove the decision to add an SMT line last year. We’ve placed a second line on order because we continue to see very strong demand for capacity,” said Dan Camp, VP Acuña/Del Rio Operations.

Each line features a DEK Neohorizon 03iX printer, a dual head ASM Siplace SX2 chip shooter, an ASM SX2 odd-form part placer and a BTU Pyramax 100N nitro- gen reflow solder system along with shut- tle conveyors for automated board handling.

“We’ve configured these SMT lines for high volume assembly with minimal product han- dling during that process. The equipment is easy to reconfigure for changing product mix and upgradeable should our customers’ needs evolve,” said Ricardo Guerra, the facility’s SM/A-I Manager.

The DEK printer includes precision optics, semi- automatic stencil load and an understencil cleaning system with a core cycle time of 8 seconds. The Siplace chip shooter can place components as small as 0201 and all of the SX machines have modular configurability via their SX gantries. The BTU Pyramax nitrogen reflow oven has 8 top and 8 bottom zones for precision-controlled heating.

“The new lines are a welcome addition given our current production schedule. Our growth is a testament to the hard work of our team. They’ve managed to maintain high customer satisfaction in a very challenging environment,” added Dan.
