- But this can be a destructive process so will require a sample PCBA from the outset. The PCBA will then be run through the reflow oven with thermocouples attached to a data logger . It's important that that the data logger is positioned correctly so that it doesn't affect the movement of the PCBA through the oven .
- Comments on inspection methods for PCB testing. Manual testing is phasing out. In contrast, electrical testing is more accurate when looking for a short circuit or open circuit faults. Visual test can be more easily detected problems in the early stages of production process. Thus, visual test can ensure the highest product percent of pass.
- We have a quality assurance team to monitor, inspect the processes and support continual process improvement. We currently employ numerous advanced test equipment including tests of AOI Testing, Visual inspection, X-ray Inspection, In-Circuit test, and optional Functional Testing to produce high-quality and cost-effective assembly.
- Reflow Soldering. Soldering oven – When the surface mounting process is over, the PCB enters a reflow soldering oven. Preheat zone – The very first zone inside the reflow oven is the preheat zone.In this zone, the board’s temperature plus that of all the components attached to it raises gradually and simultaneously.
- The common test stations that are built into a typical SMT flowline would be: Bare board testing – this can be achieved with an Image Subtraction Method. Solder Paste inspection – options include high speed camera through 3D scanning. ... The functional test is the final step in the manufacturing process where the finished PCBs are tested ...
