Instrumentation & Measurement

Total process control and reduced tolerances are hugely important for any technology where measurement is the primary product function.

All of the circuit boards manufactured by Momentum Circuits can be supplied to IPC Class 2 or 3 standards, but more importantly, Momentum apply tighter tolerance controls that standard to ensure that all products delivered offer continuity of physical dimensions and electronics performance.

The IPC specifications can at times be disconcertingly broad and forgiving for a manufacture of circuit boards, but the difference between top and bottom tolerance can be in the region of  20% variance. Momentum feel this is simply not enough control and is completely avoidable if suitable care is taken when selecting raw materials and manufacturing multi-layer PCBs.

For every circuit board supplied by Momentum Circuit, we supply a several page comprehensive quality report that shows all of the physical dimensions, materials, plating depths and processes confirmation.

The boards are also supplied with a cross section if required to show layer build and internal plating performance, and a solderability sample that indicated the wetting performance of the solderable finish and the PCB's resistance to delamination.

Every first batch delivered will undergo secondary inspection at the Momentum Circuits office and each pack is marked with our logo once approved.

What our customers say...

"As a customer, we shouldn't have to secondary inspect boards at all if we have paid for them to be tested and inspected; they should be perfect. Sadly in the past, this has been no guarantee of compliance and this is a cause of huge frustration with our team when testing a finished gas analysis unit and finding anomalies. The detail within the QA inspection forms for the 3x board types we purchase from Momentum would indicate that this is now a task we no longer have to carry out ourselves and we have a zero defect rate over the last 5-months of repeat deliveries. Long may this continue."
