Perfect Array and Transplant board
When delivered in array we have some parameters we need to address:
1) X-out allowed in Array : Boolean
X-out allowed is true - not true is x-out not allowed.
X-out : Required in P and Optional in the rest.
This means that the factory can deliver arrays with defect boards within rules. When allowed there should be a rule of how many boards can be defect and how many panels can have defect boards.
A typical rule is: Maximum 10% of the panels can have x-out units. Panels with x-out shall be packed in separate inner wrapping.
Others also restrict how many unit per panel can have x-out.
2) Transplant Unit allowed in Array: Boolean
Transplant Unit allowed is true - not true is not allowed. - this can be Optional for all. (product, profile and capability)
- this means the factory can replace a defect board with a good one in the array. This is quite common on complex and high cost products.
We at Elmatica have made a general rule for this process with clear quality requirements.
