My opnion is this: For new process establishment, I always use a 15% PF&D factor until such a time that the operators become experts in the assembly process. After that I will actually remove ALL PF&D allowed in the processing time. My professor, and another Lean Expert told me that the first...

Thanks PSE, We are doing both, thru hole and SMT. The boards in question are older and need to be obsoleted or re-engineered. We do have an AOI machine, but as you stated its after the fact. I have a few ideas, such as limiting the number of boards each operator is able to build, currently...

I am trying to find a training tool on standard workmanship training as it pertains to torque values, hardware stacking, hard joint verses soft joint. etc. We adhere to IPC-610 which is EXTREMELY basis but specifies electronic board assembly not the metalware associated such as the chassis...

Thanks for the input.... We DO NOT have poka yoke as far as artwork on the board itself for polarity. However we do have specific colored bins and digital photos depicting the bin color for reference to component specifics. I believe the biggest problem i am seeing as an outsider looking in is...

I am looking for assistance, my level of expertise lies in electro-mechanical assembly, I have been asked to look at our PCBA assembly process in order to implement process changes pertaining to a reduction in quality issues, and the reduction of throughput cycle times. I know nothing of board...

Thanks for the input, if I knew how to attach a document to this responce, i think you all would like what we create here as far as digital work instructions go, however, as stated before it is time consuming. thanks again.

IHaveNoSpaceBar One peice flow is exactly as stated. The 1st step to modifying ANY process is you need to see it. I would recommend you spend the time necessary and document each step in the process, document the cycle time at each station/machine, the travel distance between...

Yes I have a template, but i have to import each picture, write the text, tie the pic to the text, ect, ect. I used a software before that you type the text, associate it to the pic number, and press a button and is ties the pic to the text, and constructs the WI's for you, it was a wonderful...

If you know your takt time, do you know what your actual build times are? If you divide your build time by your takt time that will give you a basic head count. I dont know if you are doing 1 peice flow or batch. But if your assembly cycle time is 226 minutes (for example) and your takt time...

I agree, anytime value added labor is used to create something the customer is willing to pay for, there should be an accompaning work instruction. I know my common practice is to have a well seasoned assembler perform what i call a "control build" where we sit and document step by step...

Currently I am using MS Word and digital photos with minimal verbage to depict assembly methods. Although this is highly effective, and the operators love them, they are extremely labor intensive up front. My question is, does anybody know of a any work instruction software that will compile...
