Along with golden devices to confirm proper system operation, we recommend these practices:
a) Run Diagnostics Daily
The best maintenance practices involve these daily maintenance utilities:
Replace probe card with loopback card & run main diagnostics
It typically takes between 5 and 10 minutes per machine, and is well worth the time, as doing so significantly reduces the probability of bad data due to some unanticipated fault. The key is to establish known good system performance.
b) Keeping Software Updated
The newer software does not overwrite old diagnostic reports so previous diagnostic test data can be referred to if an issue appears. The newer software also incorporates many updates to make the system more robust by preventing false failures and flagging marginal failures that may otherwise not be flagged. The tests do not take that long to run and having the data makes it easier to troubleshoot in the event something changes and a problem occurs. Having records permits rapid analysis of shifts.
c) Problem Isolation
When problems occur, the system self-test software determines if there is a fault in the system and what might be causing it. Maintenance personnel ought to be familiar with running all diagnostic utilities, digital module tests and module calibration. Process test results should not be the criteria for determining if there is a hardware fault. If swapping a module is necessary to isolate a fault, good practice dictates recording of module serial numbers and pre/post test results. In numerous cases where multiple modules were swapped, the wrong module has been sent in for repair.
d) Log Book Maintenance
Log books also should be maintained so that the information about a specific module can be recorded. As modules are interchangeable, data that shows VFIF-16 #3 was swapped is not much help. The serial number is needed.
The loopback plug is a handy tool to use if the PAC or loopback card is suspected of causing diagnostic tests to fail. The TAC plug allows the system performance to be confirmed without a PAC installed. The loopback plug is for CPM based systems only.
The plug is priced at $4,300 and make sure to specify whether you have a CPM or PAM matrix.
P/N 11094 Shielded Extender Module
The shielded extender module is used for all Reedholm systems. Card guides are put on the sheet metal so that both vertically and horizontally installed modules will be properly supported. For example, the same performance is provided in a bench-top RI-40 modular chassis as in a seven-foot RI-51 TDDB system.
Reedholm’s SelfCal module (SCM) provides a simply way to link accuracy of dc instrumentation in a Reedholm system to that of an external digital multimeter. If the accuracy of the digital multimeter (DMM) used to calibrate the SCM can be linked to a certified calibration laboratory, the accuracy of the Reedholm test system can thus be certified.
The Loopback Card is a maintenance fixture that can be used to check system performance with a PAC or TAC/PAC installed.
The price for the Loopback Card is $4,300.
Even the most reliable test systems can occasionally have problems. That’s why this months newsletter focuses on helping customers maintain their investment.
We look forward to hearing from you.
Jim Reedholm – CEO
Here are four reasons why a Reedholm service agreement simply makes sense:
The average price of a non contract repair ($3,450) is 230% higher than the rate of the same repair done under contract (average of $1,500). And the service contract repair is expedited, so it is processed twice as fast.
Customers with a service contract also receive a 10% discount on the purchase of modules.
Customers with a service contract enjoy as much as a 40% discount for applications support. The service contract rate for our hourly rates for apps help ($150/hour) and development ($200/hour) while non contract customers are billed at a $250 rate (apps or development).
A contract allows customers to work from a budget and not have to chase a PO anytime a repair or help is needed.
Maintenance Training Class:
We also believe having a one to three day training class would help on the maintenance of your Reedholm system. We would be teaching the basics of how to confirm the system is working correctly, how to calibrate, and how to fault find to a problem module.
The cost of the class would be $5,000 to $7,500 inclusive of expenses, contingent on our ability to get a few other local accounts to sign up for a one day class. Of course, flexibility when scheduling from all sides is paramount. We will also need to have the test system available for the labs.
