Initial Testing

Industrial computer boards and other parts we are equipped to evaluate are tested to verify functionality and discover possible damage.

Our Process: Refurbishment

Industrial computer boards have all components with low MTBF numbers (such as capacitors and connectors) replaced and are washed in our PCB cleaner to remove dust and grime.

Our Process: Repair

Industrial computer boards are fully diagnosed and repaired by our engineers. Logs of the problems encountered and solutions implemented are recorded.

Our Process: Final Testing
