Increasing Production and Reducing Processing Time in PCB Assembly
Challenge
Improve Efficiency of Aerospace Printed Circuit Board Assembly
A manufacturer specializing in aerospace PCB assembly wanted to improve their efficiency and throughput by reducing overall processing time while lowering labor costs. The customer's original method involved a 10-step procedure including premixing materials, applying ruggedizing materials, manual masking, application of conformal coatings, and lengthy heat-cure times for each side of the PCB. The customer's total process time was 210 minutes and the heat-cure time was 360 minutes for each board, and with two people, the throughput was only 16 PCBs per day.
Solution
Removed the need for masking and reduced process steps by applying a UV light-cure solution with automated dispense
The Dymax team, including the territory manager, sales partner and application engineer, met with the customer to review their assembly process and understand their manufacturing needs. After listening to their challenges, the Dymax team recommended a UV light-cure solution with automated dispense and cure options to meet their efficiency goals and expectations. The proposed products included Dymax dual-cure 9481-E conformal coating and 9309-SC ruggedization / reinforcement adhesive. To eliminate the manual masking step, a PVA Delta 8 dispensing robot for precise application of the materials was incorporated into the process along with a Dymax UVCS 12" conveyor with Fusion F300 lamps for fast UV curing of the printed circuit boards.
Resultados
Reduction in processing time by 97%, increased production by 231% and doubled throughput
By switching to light-curable materials, removing the masking step, and implementing an automated process, the customer was able to:
- - Reduce the total processing time by 95.7%, from 210 minutes to only 9 minutes.
- - Increase production by 231.3% and save 871 hours per year.
- - A light-cure solution eliminated the lengthy heat-cure process, mixing time, and provided an environmentally friendly green process.
