Core Responsibilities

Primary Functions

Perform complex rework, repair, and modification of printed circuit boards (PCBs) and electronic assemblies according to IPC standards.
Utilize advanced hand soldering and de-soldering techniques for both through-hole and surface-mount (SMT) components, including fine-pitch and leadless devices.
Work under a high-power microscope for extended periods to perform intricate soldering, component placement, and trace repair on densely populated boards.
Remove, replace, and re-install a wide variety of electronic components, including BGAs, QFNs, and other leadless packages, using specialized rework stations.
Execute engineering change orders (ECOs) by modifying assemblies, which may include cutting traces, adding jumper wires, and replacing specified components.
Inspect and diagnose non-conforming assemblies to identify the root cause of failures using schematics, multimeters, and visual inspection tools.
Interpret and follow detailed work instructions, assembly drawings, bill of materials (BOMs), and schematic diagrams to ensure all rework is performed to specification.
Handle and process delicate electronic components in an ESD (Electrostatic Discharge) safe environment to prevent damage and ensure component integrity.
Perform Ball Grid Array (BGA) rework, including component removal, site preparation, re-balling, and precise replacement using BGA rework systems.
Conduct thorough visual and dimensional inspections of reworked areas to verify conformance to IPC-A-610 quality standards and specifications.
Maintain accurate and detailed digital and paper records of all rework and repair activities performed on each assembly, often within a Manufacturing Execution System (MES).
Mix and apply epoxies, conformal coatings, and other bonding agents as required by the assembly and rework instructions.
Use a variety of hand tools, power tools, and specialized rework equipment, such as hot air pencils, pre-heaters, and solder-suckers, with high proficiency.
Identify and properly tag non-conforming material, and escalate recurring or systemic issues to engineering or supervisory staff for root cause analysis.
Manage time effectively to complete assigned rework tasks within established production schedules while maintaining the highest quality expectations.

Secondary Functions

Assist in the training and certification of other assemblers on specific rework techniques and proper soldering procedures.
Collaborate with Quality Control Inspectors and Process Engineers to provide feedback on common assembly defects and suggest process improvements.
Maintain a clean and organized work station, adhering to 5S principles and all company safety protocols.
Participate in root cause analysis activities to help identify and eliminate the sources of manufacturing defects.
Verify that tools and equipment are properly calibrated and within their valid certification period before use.
