Quality is of paramount importance to us. This means that our factory heavily invests in state-of-the-art equipment. This increases our efficiency, our control, which in turn, helps us to make quality PCBs.
Of course, we also include various controls throughout the production process:
As soon as your gerber files are provided, our team of highly trained CAM Engineers will review them. Ian case of any doubt & before proceeding to production, we will get back to you & send you our Engineering Questions (EQ). This to ensure, that we fully understand your requirements.
This term stands for Electrical Test. 100% of all our PCBs will go through an electrical test. This will ensure that all PCBs will have no short circuits, nor any open circuits.
We have 2 options to perform this test:
For smaller volumes (below 3sqm): we perform the test with flying probes. Flying probe test systems are often used for the smaller volumes. This type of testing uses electro-mechanically controlled probes to access each circuit of a PCB.
- Pros: low cost, as no fixture is required and also quick to implement.
- Cons: long testing cycles, as circuitries of a PCB are tested one after the other.
For larger volumes (above 3sqm): we perform the electrical test with a Bed of Nails tester. A bed of nails tester is a traditional test fixture, which has numerous pins inserted into holes in an epoxy laminated structure. These pins are aligned to make contact with test points on the printed circuit board and are also connected to a measuring unit by wires.
Pros: fast testing, as the whole PCB is tested in a split second.
Cons: it takes a longer time to build the tester.
Automated optical inspection (AOI) is an automated visual inspection of PCB inner layers. A camera autonomously scans the inner layers and compares the results to the original gerber files. It is commonly used in the manufacturing process because it is a non-contact test method. The AOI check the inner layers for line width violation, spacing violation, missing pads, short circuits, open circuits, cut and hole breakages.
X-ray inspection is a technology based on the same principles as AOI. It uses X-ray as its source, instead of light to automatically inspect features, which are typically hidden from view. This is particularly useful to verify layer displacements after pressing multi layer PCBs.
Copper tracks on PCBs are more and more used as transmission lines with clocks rates above 5 Gbps & frequencies above 5GHz. A copper trace’s width & thickness strict control will ensure stable impedance.
