Altest PCB Testing
Altest entire spectrum of testing equipment ensure complete functionality and deliverability of your PCB design.
At every stage of production, we run a series of checks to ensure that you have an end-to-end hassle-free experience.

AOI (Automated Optical Inspection)
- AOI (XL / 3D) provides the quick and precise inspection required to ensure that the product is of high quality without any manufacturing defects.
- 3D Inspection
- Board Size: 850mm x 610mm (33.46” x 24”)
- AOI systems use cameras and image processing software to inspect PCBs for defects. They can detect issues like soldering faults, missing components, and incorrect placements. AOI is particularly useful for high-volume production, where manual inspection would be impractical.

Flying Probe
- Flying Probe Test is an electrical PCBA test.
- Flying Probe Test Requirements
- Visual Tests for component presence, absence, and rotation
- CAD data: ODB++(Ver 7), IPC356, or Allegro ASCCI file
- Test ICs for open tracks on the PCBA
- Schematic file for troubleshooting the PCBA
- Isolation Test to detect shorts on the PCBA
- Standard analog in-circuit test

3D X-Ray
- The 3D X-Ray tool enables us to inspect components that may not be visually accessible from the top and/or bottom.
- Detect Solder Bridge’s, Cold Solder and Voids

Functional Test
- Continuity Test
- AC/DC Voltage Test (Input and Output)
- Electrical Test to duplicate or reproduce the incorrect operation of the component.

- Before any electrical testing, a visual inspection is conducted to identify obvious defects. This includes checking for solder bridges, alignment issues, and surface contamination. A keen eye can catch many potential problems at this stage.
- Functional testing simulates the PCB's operational environment to verify its performance. This step checks if the PCB operates correctly within its intended application, ensuring it meets the required specifications.
