The specification below provides the recommended improvements needed to improve product durability. They are ranked from bronze to gold based on the effectiveness of the change in improving durability, with bronze being the minimum and gold being the maximum.
Better design and manufacture of PCBs and connectors
PCB inspection to IPC610E / IPC-J-STD-001; ZIF connectors
Self-diagnostic fault codes on TV display where component fails
Ask for clear evidence of meeting the requirements listed above, e.g.: technical specifications, drawings, photographs; test data (ideally from an independent test house), quality control data.
* Lifetime test: 10 TVs to be tested to operate without failure in 100% of cases, in normal operating conditions for 4 hours per day on-mode for a simulated 3 years of operation, with 30 min cool down between sets.
Improved reliability of components can reduce early returns and improve brand reputation which, in turn, can lower business costs and increase long-term sales.
To calculate overall cost savings for your business, use the WRAP cost/benefit analysis tool (currently in draft form and available on request).
Increase strength and rigidity for TV casing
Small changes to mouldings and material specification should only add a few pence, assuming tooling change is minimal.
This is largely a programming /design issue and should add very little cost
Surface mount technology
The use of surface mounted components could add a significant cost depending on the volumes made and production techniques available in the factory.
Use of steel chassis to support PCB
Extra drillings in a steel chassis should add minimal cost.
PCB testing and inspection
Any testing and inspection will add cost in terms of rig time and labour costs.
IC/Chip ZIF connectors
These are a little more expensive than regular connector blocks but reduce the risk of IC damage.
