PTBA Solder Assessment

Information

Equipment and Materials

Review the operators knowledge of the solder equipment. Record photographic evidence of solder equipment being used by operator.
Ask the operator to explain and demonstrate the process of solder iron tip maintenance, and 5s standard for solder work station. Was the operator able to explain and demonstrate solder tip maintenance process to IPC-A-610 standard? Was the operators cleaning sponge clean and clear of debris? Was the solder operators work area clean and clear of solder debris? Record photographic evidence.
Ask the operator to explain how they verify correct solder is being used? Operator should be able to explain that solder type is stated on the TKN files. Record photographic evidence of TKN File that references solder type and photograph of solder type being used by operator.
How does the operator verify correct type of Flux is being used? Record photographic evidence of flux container with type of flux identified on the container.

Detail Yaskawa solder training completed by the operator. Review training records with HR. Record photographic evidence.
Has the operator completed Yaskawa multimeter training PTB019? Review operator training records in HR. Record photographic evidence.
Has the operator completed record sheets QA1322 Multimeter check sheet and QA1328 Solder Iron check on a daily basis. Record photographic evidence.
Ask the operator to show document QA1202 Yaskawa Soldering Standard Reference Booklet that shows and describes common types of solder defects? Was the operator able to provide a copy of QA1202? Did the operator understand the purpose of the document? Record photographic evidence.
Ask the operator to show the documentation that explains the IGBT pin layout that has to be checked by the multimeter? Was the operator able to produce a copy of the Cosmos PCB Continuity Guide EWI01195? Did the operator understand the the purpose of the document. Record photographic evidence.
Verify the operator understands cosmos line QC plan?

Ask the operator to explain and demonstrate the process of solder iron verification checks and where these checks are recorded? What is the process if the solder iron fails verification checks? Record photographic evidence.
Ask the operator to explain and demonstrate the process for multimeter verification checks and where these checks are recorded? What is the process if the multimeter fails verification checks? Record photographic evidence.
Review the operators solder process technique and output? Record photographic evidence.
Verify operator is using correct solder mask during solder process. Record photographic evidence.
Review operators solder inspection techniques? Verify against solder defect booklet QA1202.
Review the operators multimeter process technique? Verify this against Technical specification EWI01195. Ask the operator explain Technical specification EWI01195.

Verify that the operator understands the risks associated with the solder process. Record solder defect types described by the operator. Record other defects to PCB described by the operator which could occur.

Verify that the operator understands the health and safety aspects of the solder process. 1. Use of LEV 2. Wear safety glasses 3. Understand safety associated with materials from safety data sheets. 4. Solder iron located in holder when not used. 5. Solder iron turned off when not used at dinner break or end of shift.
