Maintenance Technician, A typical Day in HP.
Pros: good communication system in place from shift to shift, always are energised to try resolve issues with tools down.
Cons: can louse track of time, need to stick to the recommended breaks, fresh eyes having walk away from a problem can be the solution, go over problem in your head during break and sometimes you can come up with the answer.
A typical day in work would be arrive in 15 mins early to receive a verbal pass down from the previous shift, discuss any on going Yield and tool down time issues, if there was a production tool down this would be the priority to get this back up running in a safe and timely manner, discuss the path forward at the morning meeting with relation to any tool down issues and also have a plan in place to investigate the low Yield issues, Usually by mid day the tools would be back running having passed all the CPS checks and audit of samples and passed back over to production, inform the operator and explain in clear terms what the issues were, explain to the coordinator that if there could be extra sample audit checks in place for the remainder of the shift to ensure tool is performing as intended, Inform production supervisor and Maintenance supervisor, type up a report of the problem and the fix, log details on the system for further reference if problem should occur on another machine,
continue to work on any yield issue, find root cause, examine tool and eliminate tool section by section, if nothing found, trace back up stream, ensure that the problem is not tool related, inform process tech, run a different batch of material, eliminate all possible causes material etc until you find the source, finally completed pass down and hand over to the incoming shift detailing all you have found and where you are at the moment.
