Automotive PCBA Process
1. PCB Type: 2-6 layer FR-4 rigid board; Aluminum core board for lighting applications
2. Minimum Trace Width/Spacing: 0.1mm / 0.1mm (customizable to 0.075mm)
3. Component Capability: 0201-0805 packages; through-hole connectors; 0.4mm pitch QFP
4. Soldering Technology: Lead-free reflow soldering + wave soldering for THT components
5. Inspection Methods: 100% AOI; manual visual inspection; in-circuit test (ICT)
6. Protection Process: Acrylic conformal coating; selective potting for connector areas
7. Reliability Standard: AEC-Q100 compliant components; -40 to 105 operating range
8. Management System: IATF 16949 quality system; full batch traceability
Automotive PCBA Application Scenarios
1. Body Control & Comfort Electronics
Widely used in body control modules (BCM), the PCBA manages vehicle functions including central door locking,
power window control, seat adjustment, wiper control and HVAC system, realizing integrated management of
vehicle comfort electronics and improving driving experience.
2. Vehicle Lighting & Power Distribution
Applied in automotive lighting control units and power distribution boxes, the assembly supports LED headlight
control, ambient lighting drive and fuse box power management. With excellent vibration resistance and thermal
stability, it ensures reliable operation of vehicle electrical systems in complex road conditions.
Automotive PCBA Production Line
Our dedicated automotive electronics assembly lines are configured with high-speed SMT placement systems and automatic wave
soldering equipment, suitable for mixed assembly of micro surface-mount components and plug-in connectors. We implement strict
ESD and dust control in the workshop, and carry out first article inspection (FAI) and batch sampling according to IATF 16949
requirements. The production process supports flexible switching between multi-variety small-batch and mass production, meeting
customized demands of different automotive electronic projects.
