Underwriting our boards

Momentum Circuits are confident with our manufacturing capabilities and go to extraordinary lengths to ensure that everything supplied is not only fit for purpose, but also meets the industry requirements for the technology in question.

Based on this, we offer a guarantee/underwrite on the PCBs that we supply that offers to cover the component value on the boards and a limited labour cost of assembling the board (specifically surface mount or through hole times) in the event of a PCB related failure.

Our intention is to avoid any customer having to cover component loss at their expense, but it is not our intention for anybody to profit out of a non-conformance situation. To this end, we also expect our customers to carry out a first article inspection and check the approval data to ensure that what we have manufactured matches your expectations.

This is not something we would anticipate being a regular feature of dealing with us, but we want to give our customers peace of mind when using Momentum Circuits and this is a unique offer in the UK PCB industry.

How does the guarantee work?

If we have supplied boards that exhibit open or short circuits (bearing in mind we 100% electrically test all product to NET list), or if a board delaminates when processed within the recommended temperature/time profiles, we will offer to not only replace the boards in the fastest possible time, but we will also cover the standard cost of those components that are not recoverable up to a maximum of 10x the bare PCB value.

What DO we cover?

1. The replacement cost of the board (free issue replacements.)

2. The cost of surface mount and conventional components that cannot be reasonably or reliably harvested off a faulty board based on a standard lead time and volume MOQ.

3. The cost of populating the PCB element of the assembly only (ie. specifically the time in surface mount and/or through-hole assembly for the bare board)

4. Due to the potentially disproportionate cost of components to the value of the bare PCB, our factory's maximum liability will never exceed 10x PCB value.

What do we NOT cover

1. Premiums for purchasing components on fast lead times or in small volumes

2. Profit margin on components  or labour rates (charge out rate Vs actual labour cost)

3. Production down time

4. Test and inspection time

5. Deliberation, fault finding time or 'thinking time'

6. We absolutely do not accept the concept of 'total batch rejection' as part of a claim based on the typically higher value of components relative to PCB price. Only qualified faults will be underwritten subject to the terms & conditions of this agreement. It is also expected for our customers to inspect the delivered boards and check the technical specification and layout of the design upon receipt of the stepped data sent back for approval before commencing any population.

As with all PCB assembly, there is a reasonable expectation for an OEM or assembly house to build and inspect an individual new product to ensure suitability for process, profile and stability after thermal shock before populating a total batch of products.

This 'due diligence' measure reflects the care we take to go through pre-manufacturing DRCs and EQs to avoid failure claims that might be excessive.

Clearly we have to limit our liability reasonably to the PCB element of a build only as we have no control over the labour rates applied by our customers and we cannot cover the costs associated with non-PCB related assembly, product build or other aspects of the box build. If we supply a small connector boards used in an aircraft that exhibits a fault, we do not expect to cover the cost of building the whole aeroplane for example, regardless of what that cost might be.

This offer is extraordinary and hopefully shows considerable good will. We need to qualify any claim on behalf of our factory in the unlikley event of being in this situation as part of our commitment of care to them.

We cannot and will not support opportunist claims that transfer the total cost of a manufacturing operation to Momentum Circuits and our factories because this is a good will gesture, not an opportunity to maximise the return on a rare & unfortunate situation. 

Momentum Circuits do understand that problems cost money and this offer is made to limit some of the costs involved.

We do not hide behind offers of 2 or 3x the bare PCB cost because this does not come close to covering a total problem in most cases, but similarly, we cannot realistically cover the full cost of our customer's operation and therefore this is hopefully a measure that goes further than most to give you peace of mind in the event of a problem.
