Hi guys,
I work for a small sub-contract semiconductor manufacturing firm and I would like to ask for help from you about starting a Control Plan for specific toolings that we have in the production shop. This is a first as we do not have one. What we have as Control Plan is Control Plan for production process.
What needs to be considered on a specific tool like a mold tool? (not necessarily a semiconductor mold tool, any tooling like punch and die or stamping tool would do as long as it is critical to your process)
If you guys have a sample of such a Control Plan for Mold Tooling, well not necessarily mold tooling, maybe just a sample pertaining to a specific tool (critical tool is preferred) so I can base that on our manufacturing toolings.
Here is what our blank control plan sheet looks like but this one is tailored made for a specific customer's manufacturing process.
This is not my normal work as I am a technician but now the team is involving me in this endeavor. I would like to contribute as much as possible and learn how to make one.
Among the existing controls for tooling parts for punch/die sets are the tool life data spc which is derived from:
a. number of hits (SPC trend chart)
b. surface(side) measurement of punch / die tooling to determine wear (SPC trend chart)
For mold toolings we have:
a. number of shots
b. plunger pot diameter (SPC trend chart)
c. plunger tip diameter (SPC trend chart)
Plunget pot data
Number of shots (Mold)
Plunger tip data
Now for mold there are other parts of the mold tool like the mold chases (top/bottom) which do not have control at the moment. I just know that they are refurbished when damaged which is about yearly.
I know the data I provide is insuffucient at this time but I'd like to ask for help how you preventive maintenance/equipment guys do it and if possible share some samples from which I can help derive a better control plan.
Any inputs and sample share will be a great help for me
Thanks
