PCB Assembly Testing and Inspection

Manual Visual Inspection

PCB assembly testing and inspection can reduce processing risks. Manual Visual Inspection is one of the inspection methods. Manual Visual Inspection can be achieved at every step of the PCB assembly process.

PCBA Manual Visual Inspection

Modern PCB assembly manufacturers offer many sophisticated testing and inspection methods to verify the build quality of printed circuit boards. JHYPCB is proud to offer a wide range of PCB testing and inspection services, including Automatic Optical Inspection (AOI), X-ray inspection, functional testing, burn-in testing, in-circuit testing, manual visual inspection, etc. Advanced PCB assembly testing and inspection help us guarantee the quality of all current PCB projects.

Manual visual Inspection from JHYPCB

Manual Visual Inspection is the simplest type of PCB inspection that we carry out in our production facility.

We have been able to invest in our quality assurance department to ensure that our Manual Visual Inspection (MVI) processes are optimized. For this type of test, the PCBs are checked thoroughly by a quality assurance worker. This means inspecting the PCBs either through magnification or with ordinary eyes. during the inspection process, the PCBs are compared to the specifications in the documents. This is to make sure that the final design meets all the specifications. During this process, the inspecting officer will also check for possible defaults. This inspection process helps us to spot any possible defect.

JHYPCB performs MVI almost with every step during the production process of the PCB, especially during the assembly process. We conduct this inspection with every board that is produced in our modern facility. Furthermore, as a part of our unique quality policy, we also perform other elaborate tests on the board.

During the MVI, the quality assurance staff will inspect almost all the parts of the PCB. They will be able to look for potential defects in this board. When it comes to JHYPCB, we have a peculiar MVI checklist. Our MVI checklist involves:

  • Validating the thickness of the boards for correctness. This also means verifying the surface roughness.
  • We also verify that the assembly dimensions are in agreement with the specifications. We also ensure that the dimensions for the electric connectors are correct.
  • We verify the clearness and integrity of the conductive patterns. We check for voids, burrs, open circuits, and solder bridging.
  • Verify the quality of the PCB surface, and also check for possible pinholes, scratches, dents, pits, and different other defects.
  • We ensure the verification of all right placing of the vias. We check that they have been punched correctly while ensuring that the diameters are in agreement with the specifications of the design. We also ensure that the PCBs are devoid of nodules or voids.
  • Our MVI quality procedure confirms and validates the brightness, roughness, and firmness of the pad plating. We also check for defects such as bulges.
  • We also assess the quality of the coating. We also inspect the colour of the plating flux. We check for its correct placement, firmness, and an even profile.
