About The Position

This is a low-volume, high-mix, high-complexity electronics manufacturing environment focused on PCB rework and hand soldering. Soldering is done with a high lead alloy (93.5% lead, 5% tin, 1.5% silver), melting at 300 degrees Celsius (572 Fahrenheit) with preheating. The role involves performing both through-hole and surface mount soldering/rework on PCBs with identified defects and required rework steps. Technicians must verify defects against IPC and J. Std. requirements before completing repairs. Verification is done visually and on an X-ray machine. Conformal coating is already removed. Work includes surface mount and through-hole soldering, hand soldering, use of pre-heaters, soldering irons, hot air pencils (when qualified), resistive tweezers, desolder guns, specialty tips, and general assembly tools. Technicians must have experience with pre-heaters and desolder guns. Boards are complex, with components ranging from 0201 to 0603, J-leads, 100L TQFPs, jumper wires, fine-pitch components, BGAs, capacitors, resistors, and high and thermal mass connectors. Boards are multi-layer, ranging from approximately 5–30 layers. Summit or Ursa BGA experience is highly preferred. Common defects include tombstones, low solder fill, solder balls, solder bridges, full-fill issues, excessive solder or flux, poor cleaning, fractures, hot tears, and class 3 solder joint concerns. Post-rework quality steps include visual inspection and X-ray inspection for hidden joints. Work then goes through QCI for review. Everything is performed under magnification, generally up to 10x. Technicians document work completed, soldering iron used, repair notes, labor, and work order tracking in a software called GSF. Basic computer skills and Excel proficiency are important. Work is seated for the duration of the shift, with energy breaks available. Candidates must be comfortable working in an ESD-controlled environment. There are no instructions on how to do the work, only what needs to be reworked and repaired, requiring a high level of rework experience to determine how to remove and resolder components. Will also set temps and load boards into bake ovens for curing. Other tools used include a torque driver. Technicians must be coachable, communicative, flexible, reliable, and able to take feedback well. Attendance is a critical expectation.
