Testing & Quality Engineering

In-circuit, functional, end-of-line, and reliability testing with full MES traceability

‍

Test strategy decides whether an HMLV program holds yield through ramp and stays out of field-failure escalations. The right test stack is rarely about more coverage — it's about choosing the right test layer at each cost and access boundary. Indic operates a full in-house test engineering capability across manufacturing-defect, in-circuit, functional, end-of-line, and reliability test, all bound to MES traceability.

‍

1.  Manufacturing-Defect & In-Circuit Testing

‍

For programs where low test access or low volume makes bespoke ICT fixtures uneconomical.

‍

In-Circuit Test (ICT) & Boundary-Scan

‍

ICT ·  IEEE 1149.1 boundary-scan / JTAG  ·  Bed-of-nails fixtures with versioned recipes and limits, rollback discipline  ·  Test-point coverage matrices.

Builds: PCBA    ·    Certifications: IPC-9252, IEEE 1149.1, IPC-A-610Class 2/3

‍

Manufacturing Defect Analyzer (MDA) & Flying Probe Testing

‍

MDA ·  Flying Probe Testing for designs with thin or absent test specs ·  Dynamic probe access to multiple nodes without dedicated fixtures.

Builds: PCBA    ·    Certifications: IPC-9252

‍

Automated Optical Inspection (AOI) & X-Ray

‍

3D AOI on double-sided assemblies (Magic Ray VS300 single-pass top + bottom)  · WATS analytics on AOI for defect-escape reduction  ·  X-ray inspection for hidden joints (BGA, QFN).

Builds: PCBA    ·    Certifications: IPC-A-610 Class 2/3

‍

IN PRACTICE

‍

On a smart-city street-lighting program with no test specs and limited test points, Indic adopted Flying Probe Testing to reach 97.78% coverage on a 4-board PCBA module — without bespoke fixtures, and against a Phase 1 outsourced MDA result that had stopped at ~50%.

‍

2.  Functional & End-of-Line Testing

‍

For OEMs where final functional behavior and escape prevention decide field reliability.

‍

Functional Test (FCT)

‍

FCT  built around customer test cases  ·  Custom fixture design with guide-pin and pre-centering precision  ·  Test software validation against golden units  ·  Lab VIEW automation, remote diagnostics, role-based access.

Builds: PCBA + Box-Build    ·     ertifications: IPC-A-610 Class 2/3

‍

End-of-Line(EOL) Test & Hi-Pot

‍

EOL test ·  Hi-pot test per IEC 62368-1 for power-electronics safety  · Deterministic test sequences, versioned limits with rollback.

Builds: PCBA + Box-Build    ·    Certifications: IEC 62368-1, IPC-A-610

‍

On-Board Programming (OBP) Integrated with MES

‍

OBP runoff the tester critical path for throughput gains  ·  Serial-bound programming records  ·  MES traceability per unit, ISA-95 aligned.

Builds: PCBA + Box-Build    ·    Certifications: ISA-95 traceability

‍

IN PRACTICE

‍

For a Mahindra EV charger functional-test bottleneck, Indic separated programming from FCT and moved programming to lower-cost stations running in parallel — +60% throughput, -20% direct test cost, no new capital equipment.

‍

Reliability Testing + Cross-Segment Capabilities

‍

3. Reliability & Environmental Screening

‍

For products that face harsh field environments and need pre-shipment qualification under real-world stress.

‍

Environmental Stress Screening (ESS)

‍

Thermal cycling  ·  Burn-in  ·  Vibration screening  ·  Pre-shipment qualification for industrial, EV, and safety-regulated products.

Builds: PCBA + Box-Build    ·    Certifications: IEC 62368-1

‍

Hi-Pot Test & Safety Compliance

‍

Hi-pot per IEC 62368-1 for power electronics  ·  Safety isolation verification  ·  Class-conscious workmanship inspection per IPC-A-610.

Builds: Box-Build, harness-integrated    ·    Certifications: IEC 62368-1,IPC-A-610 Class 3

‍

Reliability Documentation & Customer Audits

‍

Audit-ready evidence packs (by-serial logs, fixture IDs, recipe/limit versions) ·  Operator certification records  ·  CAPA / 8D for field-failure root cause and corrective action.

Builds: PCBA + Box-Build    ·    Certifications: IATF 16949, PPAP/APQP where applicable

‍

IN PRACTICE

‍

On a renewables-sector PCBA program with random FCT failures, Indic traced the root cause to mismatched guide-pin diameter and added a pre-centering fixture upgrade— +7% first-pass yield, +8% throughput, random failures eliminated, paid back within the same quarter.
