Overview

Precision Assembly for Automotive Electronics

Our ECU assembly lines bring PCB handling, dispensing, housing assembly, screw tightening and testing together in one controlled flow. Each unit is tracked by its serial number from the first station to final test, giving you complete process history for quality audits and warranty analysis.

Typical Line Stations

Each station is engineered to your ECU design and output target.

PCB Loading & Identification

ESD-safe PCB loading with barcode / data-matrix scanning to start the traceability record.

Connector Press-Fit

Force-monitored press-fit of connectors and terminals with pass/fail evaluation.

Thermal Paste & Gel Dispensing

Programmable dispensing of thermal interface material with bead and volume verification.

Leak Testing

Air-decay leak testing to confirm the sealing of IP-rated ECU housings.

Housing Assembly & Screwing

Automatic screw feeding and tightening with torque–angle monitoring and sequence control.

Functional & EOL Test

Integration with your functional test software for final electrical verification and labelling.

Process Flow

How an ECU Is Assembled

A controlled, traceable flow from bare PCB to tested and labelled unit.

01PCB Loading & Scan

ESD-safe loading with data-matrix scan to open the unit record.

05Connector Press-Fit

Force-monitored press-fit of connectors and terminals.

02Thermal Dispensing

Thermal paste or gel applied with bead-volume verification.

06Sealing & Curing

Gasket fitting or potting, with controlled curing where required.

03PCB into Housing

Guided placement of the PCB into the housing with presence checks.

07Leak Test

Air-decay leak test confirms housing sealing and IP rating.

04Screw Tightening

Auto-fed screws tightened in sequence with torque–angle monitoring.

08EOL Test & Labelling

Functional test, result logging and label printing for passed units.
