Tombstoning on small SMT chip packages is a common defect in electronic manufacturing. Multiple contributing factors can cause this phenomenon including varying thermal mass between opposing pads. The reflow profile can have a direct impact on tombstone occurrences. Two common industry profile techniques are used to compare the effects on tombstones with end of line defect data. Visual verification is done by duplicating test profiles on a rework station. The results show a clear benefit of one profile technique over another to reduce tombstoning.
OVERCOMING TOMBSTONES DUE TO THERMAL INEQUALITIES
We recently toured Winona Area Chamber members through our Lewiston facility. Our goal was to show our diverse technology and expertise in electronics manufacturing. After a brief introduction to our integrated services, we demonstrated surface mount and through hole placement processes. It was exciting to demonstrate new equipment recently installed such as 3D automated optical inspection and our smart inventory storage system. All participants were extremely impressed and we enjoyed the show and tell time!
All coworkers enjoyed a company cookout and received a commemorative glass set displayed by General Manager, Corey Beech and President, Steve Craney.
We greatly appreciate our customers and coworkers. Thank you for being a part of our success!
