All-in-One – the lab inspection angle



4th October ,2021

PCB Technologies has been dedicating resources in an All-in-One solution. The idea is to provide comprehensive service, spanning from PCB design, through PCB assembly and full systems integration. This post provides the lab inspection angle of this holistic approach. As we all know, the production process of high end/high reliability electronic systems requires ongoing inspection and up-to-date lab equipment.

Three main verticals are fundamental in order to get the optimal test & inspection of the process end-to-end:

1. A solid quality & inspection plan throughout the entire production process.
2. Detailed definition of the interfaces between all inspection steps to optimize risk assessment and root cause analysis.
3. Continuous feedback to enable improved yield and system performance

To support these, we have three operational labs:

1. Chemical lab – inspecting wet chemical procedures and materials involved in the production process.
2. Metallographic lab – inspecting panel coupons and boards: cross-sections, surfaces, plating, hole fillings and lamination, as well as final product inspection
3. HATS (Highly Accelerated Thermal Shock) lab – inspecting PCB coupons for PTH and via reliability.

Lately we have geared up and purchased new state-of-the-art equipment aimed at optimizing and automating our chemical inspection procedure, to which we are committed as per IPC standards and customer’s requirements. These three new machines cover around 60% of all inspections. Their evident advantage relies on the utilization of our information systems documenting all the inspections and their results. This way we are able supply our customers vital information when necessary (during audits for example).

We conduct inspections throughout the production line. Our engineering team sets the order and frequency for the inspections for each and every product. Conducting this high number of inspections guarantees online identification of framework deviation, thus preventing accumulated errors that have the potential of bringing production to a halt. We will not make any compromises when it comes to quality!

Our new equipment:

1. Ionic Contamination inspection machine - reviewing production line preparation prior to the solder mask plating. We can also supply this inspection for PCBA.
2. Elongation and peel strength tests machine – performing tests according to IPC standards, aimed at reviewing copper elasticity required in order to comply with alteration occurring in the PCB while using it.
3. Titrator– enabling the execution of large scale automated chemical inspections in a speedy manor. One of its main advantages is the level of accuracy.
