specializing in fine-pitch micro-soldering to join our hardware engineering team. In this role, you will be responsible for precise assembly, modification, replacement, and repair of complex Surface Mount Technology (SMT) and Through-Hole (TH) printed circuit board assemblies. You will work extensively under high-magnification microscopes to execute delicate
micro-soldering procedures
on high-density assemblies.
Key Responsibilities
<ul>
<li>Micro-Soldering &amp; Rework:
Perform precision hand soldering, desoldering, component replacement, and rework on
fine-pitch
components (including
0201/01005
passives, QFNs, BGAs, WLCSPs, and ultra-fine pitch ICs).</li>
<li>BGA Rework &amp; Inspection:
Operate
BGA rework
stations for component removal, reballing, site preparation, and alignment. Utilize X-ray inspection equipment to verify solder joint integrity, voiding, and alignment.</li>
<li>PCB Repair:
Execute advanced trace repair, pad restoration, wire jumper installation, and ground plane repair using micro-drilling and conductive adhesives/epoxies where necessary.</li>
<li>Inspection &amp; Quality Assurance: Inspect
PCBA
work using high-magnification stereomicroscopes and optical inspection tools in strict accordance with IPC-A-610 and IPC-7711/7721 standards.</li>
<li>Prototyping &amp; Modifications: Support engineering teams by performing manual ECO (Engineering Change Order) modifications, jumper wire additions, and component swaps on prototype boards.</li>
<li>Equipment Maintenance: Maintain and calibrate precision soldering irons, hot-air rework stations, preheaters, micro-tweezers, and ESD-safe workstation gear.</li>
<li>Documentation: Track rework history, defect logs, and yield metrics in the ERP/MES system.</li>
<li>Qualifications &amp; Requirements</li>
<li>Experience: Minimum
3–5+ years of hands-on experience in precision PCB rework and micro-soldering within an electronics manufacturing, hardware R&amp;D, or repair environment.</li>
<li>Certifications: Current or past IPC-A-610 and/or IPC-7711/7721 certifications strongly preferred (J-STD-001 is a plus).</li>
</ul>
Technical Skills:
<ul>
<li>Proficiency in working under continuous stereo microscope magnification.</li>
<li>Expert-level micro-soldering skill using hot air tools, micro-tweezers, thermal strippers, and specialized solder tips.</li>
<li>Demonstrated capability to rework
0201/01005
components,
BGA/QFN
packages, and
0.4mm pitch ICs.</li>
<li>Experience reading and interpreting engineering schematics, assembly drawings, bill of materials (BOM), and ECO documentation.</li>
<li>Physical &amp; Aptitude Requirements: Excellent manual dexterity, steady hands, strong spatial reasoning, and visual acuity for fine detail. Good communication skills and the ability to work in a fast-paced engineering environment.</li>
<li>ESD Knowledge: Deep understanding of Electrostatic Discharge (ESD) prevention protocols and safe handling of sensitive semiconductor components.</li>
</ul>
Preferred Qualifications
<ul>
<li>Familiarity with basic hardware troubleshooting.</li>
<li>Ability to use CAD/board viewing software (e.g., Allegro, Altium, or similar).</li>
<li>Experience with automated optical inspection (AOI) or X-ray inspection systems.</li>
<li>Background in high-reliability industries such as aerospace, medical device, defense, or automotive electronics.</li>
<li>Familiarity with conformal coating removal and re-application techniques.</li>
</ul>
