What We Engineer

From Test Requirements to Production Test Systems

onTAP does not only sell instruments, develop software or design fixtures. We integrate test engineering around the DUT, test items, production goals and traceability needs.

Test RequirementTest StrategySoftware + HardwareFixture + InstrumentationIntegrationProduction Test

Test Strategy

Define coverage, risks, cycle-time factors and production boundaries.

Software

Develop test flow, instrument control, data logging and reports.

Hardware

Design interface boards, control boards, relay matrices and signal simulation resources.

Fixture

Bring DUT positioning, probes, interlocks and operation into the system design.

Integration

Connect software, hardware, fixtures, instruments and automation into a production test system.

Why onTAP

Why Engineering Teams Work with onTAP

Software + Hardware

Test software, embedded control, custom PCB, instrument control and fixtures can be developed and integrated under one architecture.

Custom Test Engineering

Systems are defined around DUT interfaces, signal paths, coverage and production operation instead of a single device template.

Production-Oriented Design

Beyond test function, we consider operation, maintainability, changeover, traceability and cycle-time factors.

Local Engineering Support

Supports local communication, custom development, product selection and on-site engineering collaboration without unverified 24/7 claims.
