Description Abstract This document describes the Job description for Post Title Sr. Technician – Soldering, Press‑Fit, Conformal Coating, Masking, Potting & Mechanical Assembly, based at the Company’s premises at Aitech Innovations India, Bangalore 1. Job Title Sr. Technician Role Overview Hands‑on production technician responsible for high‑reliability electronics assembly on Aitech rugged products and boards. The role covers precision soldering, press‑fit connector installation, conformal coating & masking, potting, and mechanical assembly under Class‑3 workmanship and aerospace quality requirements (IPC‑A‑610 / J‑STD‑001; ESD discipline; FOD control). Qualification Diploma in Electronics/Electrical or Mechatronics. Ability to read assembly drawings, schematics, BoMs, and work instructions (WI/SOPs); familiar with route cards and production travellers. Basic computer use for ERP/MIS data entry; exposure to SAP/ERP preferred. Strong discipline in ESD and safety practices; comfortable with microscopes, fixtures, presses, ovens, curing equipment, torque tools, and measurement instruments. At least 7-8 years’ direct experience in soldering, conformal coating & Assembly. Skills/Experience: · Soldering (through‑hole & fine‑pitch SMT rework) to IPC‑A‑610 Class‑3 workmanship and J‑STD‑001 process controls; enforce FOD controls in all operations. IPC-7711/21 certified will be preferred. · Press‑fit connector installation using qualified press, bottom & flat top tools, alignment checks, and post‑press inspection; maintain tool validation and apply X‑ray verification where required; update route card after each operation. · Conformal coating execution, including masking of keep‑out zones and defect prevention; ability to work with QA on SCAR/CAR closures when needed. · Masking proficiency (tapes, boots, liquid masks) with clean edges, proper cure, and removal techniques to avoid residue/under‑mask defects. · Potting & encapsulation: resin prep, degassing, controlled dispense, cure profiles, and void‑free results per WI/SOP; adherence to J‑STD‑001 cleaning requirements. · Mechanical assembly of boards/enclosures (fasteners, torque, thermal interfaces, staking) per conduction‑cooled enclosures · In‑process & final inspection: visual criteria, continuity/shorts checks, dimensional verification, and documentation sign‑offs per QA instructions. · ESD discipline, cleanroom/controlled environment behaviour, and recordkeeping (lot/serial traceability, traveller signatures, tool calibration records). · Proven experience as team player within a multi-site environment · Understanding of safety and equipment procedures. · Extensive knowledge of aerospace materials, components, and equipment, including their handling, storage, and transportation requirements. · Proficiency in production related activities SAP/ERP systems, and data analytics tools. · Manufacturing Process: Understanding of Manufacturing Processes, Manufacturing Time Study, Process Optimization. · Reporting: Compiling management reports on overall plant performance, and preparing MIS reports · Quality control: Awareness of ISO:9001-2015 – Mandatory, AS9100D - Nice to have. · Good communication and interpersonal skills, with the ability to effectively communicate with stakeholders at all levels. Desired Skills: · AS9100D awareness; ISO 9001:2015 quality mindset. · Experience with thermal pads/Paste, CTQs, and following customer assembly drawings (top/bottom, conformal coating maps). · Exposure to environmental testing (vibration, shock, TVAC, humidity) and ATE handling/debugging. · Familiarity with mechanical metrology, torque/angle tools, and fixture setup for precision press‑fit operations. · Time management skills to handle multiple projects, prioritize tasks, and meet tight deadlines. Roles and Responsibilities: 1. Execute production tasks (soldering, press‑fit, coating/masking, potting, mechanical assembly) strictly per Aitech WI/SOPs and customer drawings; comply with IPC‑A‑610 Class‑3 and J‑STD‑001 requirements. 2. Press‑fit operations: Verify tooling alignment, apply controlled force, perform post‑press inspection/X‑ray as specified, and record route card updates for each step. 3. Conformal coating & masking: Ensure accurate masking of keep‑out areas, defect‑free application, and participate in SCAR/CAR investigations with QA when defects are detected. 4. Potting/encapsulation: Prepare materials, control mix ratios/cure, conduct post‑cure cleanliness to meet J‑STD‑001 acceptance; document batch/lot details. 5. Mechanical assembly: Install hardware and thermal interfaces, apply specified torque, and verify fit/form/function; complete final inspection records. 6. ESD & FOD control: Maintain compliance with SOW requirements for FOD prevention, cleaning, and post‑process residue checks—no ultrasonic cleaning; meet specified cleanliness limits. 7. Quality documentation & traceability: Ensure traveller/route card completeness, calibration stickers are current, and first‑off/in‑process/final inspections are signed by QC. 8. Cross‑functional collaboration: work with QA, PPC, and Manufacturing to resolve production issues, support continuous improvement, and contribute to MIS/ERP updates as required. 9. Training & compliance: maintain skill certification (e.g., IPC‑A‑610 CIS/CIT where applicable) and participate in periodic special‑process validations (pins pressing, isolation removal, sleeving).
