How SMED on an Electronic SMT Line improved OEE?

How SMED workshop has improved the OEE from 60% to 70%.

Our client manufactures electronic products that are supplied mainly against government tenders. Having established the products in terms of quality and price, there was a spurt in demand over the past year and the current business volumes were more than 3X of the previous year. While, the downstream processes were ramped up by adding assembly lines and subcontracted activities, the upstream PCB soldering had become a constraint. The existing (Surface Mount Technology) SMT line was operating 24 x 7 and still unable to meet the full requirement. About 20% had to be outsourced at higher cost as well as increased lead time as the quality norms were being met only by an out of station vendor.
