Warranty and Satisfaction Guarantee for Rework/Repair:
BEST guarantees 100% of our contract services performed will be defect free when shipped. In the event of an exception, we will repair, at no charge, any service performed by BEST found to be defective. Simply ship the product back to us within 30 days. BEST's liability is limited to the repair of defective materials, and BEST is not liable for any other expenses or losses. As a precondition to this warranty, all outstanding invoices from BEST must be paid in full.
BGA Rework and Repair Guarantee:
BEST will request the use of development PCB's and mechanical sample BGAs in order to develop the optimal BGA Rework Profile for each project. We will charge a nominal fee for this profile development, a one-time charge that is specific to that board. Future jobs involving that same part on the same board at the same reference designator will not be charged for profiling that same part. We consider our BGA Rework capabilities to be the best in the industry; however, it is impossible to guarantee optimal results 100% of the time without the proper profile development materials. As in the automated assembly process, a profile must be developed to insure repeatability and long-term reliability.
If we are asked to proceed with the BGA rework without developing the proper profile, additional parts or work may be required to complete your job. If we need to re-ball BGAs due to a lack of developmental samples, you may be charged for the re-balling service. Please keep in mind BGAs must arrive in hermetically sealed packaging (in accordance with IPC/JEDEC J-STD-033) in order to receive a quick turn. BEST has the capability to bake BGAs but this will extend the lead-time.
