There was a time when “Made in China” was synonymous with cheaper, poor quality products. "Buyer beware" was the common theme associated with outsourcing to any Asian PCB manufacturers. So how did Epec approach this challenge and succeed? It was by managing quality through intense auditing, training, and qualification. Epec understood at a very early stage that first-class quality products from Asian manufacturers would require consistent presence, training, and auditing.

PCB Manufacturing Selection Process

One of the initial steps was to locate an office in the heart of manufacturing in China and staff it with exceptional personnel from the area. Staff in China are trained to uphold Epec’s strict policies, procedures, as well as being fluent in English, thus removing communication barriers typically encountered when dealing with overseas manufacturers. For the process of selecting the best facilities, many were visited and audited for quality, capability, and capacity – by both the newly founded Asian team and U.S. based team members.

All certifications were verified in addition to procedures and manufacturing instructions. All equipment being used must meet the highest standards, including preventive maintenance logs, and the overall cleanliness of the manufacturing floor even pointing to areas that need to be clean room environments. Material inventories and storage conditions were checked against manufacturer recommendations, with expiration dates scrutinized. Operation process parameters and records were reviewed over 6-month time frames, insuring compliance and proper actions when warranted.

Assembling Our Asia Team

A lot of potential circuit board facilities were eliminated as we narrowed down our choices. The common factor we needed to overcome was lack of manufacturing knowledge of engineered products. The best facilities and newest equipment doesn’t automatically equal good quality. A U.S. team’s presence of industry experts would need to be maintained until the chosen facilities were fully trained to the standard of efficiently and consistently producing top quality products.

Epec’s domestic team members were at the selected suppliers multiple times annually, with stays as long as 2 months. We trained our new teams to exercise proper manufacturing flow and to eliminate bottlenecks and delays. The team also fine-tuned operating parameters for the new equipment by working closely with production floor management and equipment suppliers. ISO standards were reviewed and so were our expectations with product quality.

Managing Quality with Asian PCB Manufactures

Presence and input from our U.S. quality team is part of our process to manage quality in Asia.

 

Epec employs IPC certified inspectors to install at each facility for inspection of our products only, supplied with Epec’s high quality inspection tools. The team was our 24-hour on-site ears and eyes for our products. In combination with our office staff, the on-site inspection team helps control work in process as well as ship dates.

Added Value Services

As we continue to expand our product lines and add value services, our model has not changed. We continue to control our exceptional supplier qualification procedures through onsite inspectors, quarterly auditing by our quality team, and a continued U.S. team presence. Our in depth audits review all manufacturing processes and all aspects of the quality management system. We focus on Epec’s work in process insuring the manufacturing instructions for these parts match our specifications. Raw materials used to build our parts are checked for quality and accuracy to the stated required materials. Manufacturing travelers for our orders are reviewed for proper processes and are required to receive management approval to transport work through processes. We compare reported work in process scheduling with actual production location of our orders.

Conclusion

Epec continues to use the best available technologies to advance our quality control with our Asian manufacturers. Utilizing cloud based ERP and quality systems, our Epec staff in Asia works in conjunction with our U.S. staff to supply real time data and support for all our product lines. Epec has dedicated itself to be a leader in high quality engineered products, and through our comprehensive supplier management and “committed to excellence” team, we have eliminated the “made in China” concern.
