Is there any POKA YOKA tool for selecting correct value of the small chip components during assembly.

When you say "selecting correct value of the small chip components during assembly", you are referring to caps and resistors? and that you want to know that the correct cap or resistor was place in the correct location?

your assembly is surface mount or TH's? using a machine or hand placement?

Hi

Thanks for responding to my query.

Our PCB Assembly consists of both SMD and THD components. Also,assembly will be done by machine as well as Hand soldering based on the requirement. I request you to suggest Poka yoka tool to read the value of all chip components (like resistors ,capacitors,inductors etc ) during assmenly of the PCB by Manual soldering as well as Machine soldering.

They key requirement before any fancy tools is careful storage, stock control, labeling and handling. If your parts are incorrect before they even get to production, you're screwed. As gregp suggests, to get consistently correct value and orientation of THT components you ideally need a tool like his that you kit with parts carefully and it guides you to the correct place with a laser. http://www.robotas.com/mascot/ is a similar system perhaps using a slightly simpler/cheaper concept IIRC the Versatec system automates quite a lot of the process whereas the Mascot guides the user. http://www.compuphase.com/visualplace/visualplace_en.htm this site offers some free software and some ideas for a DIY system using a webcam connected to that software. For surface mount, if you are building manually you could use a machine like http://www.fritsch-smt.de/en/products/manual-placement/sm902/ this guides you to the location of each part. For fully automated placement, on most surface mount machines, you can add a component verification unit that measures the values of components to verify what you told it was loaded is correct or additionally maintain strict tolerances. I think I would expect such a device to be $15k + labour to be retrofitted. The most sensible thing to do here however is make sure all your parts are correctly labelled, and double check your machine loadout before running a job. Typically this is done using a barcode scanner ( you scan the part label and the lane it is loaded in), these features are often optional extras. Surface mount machines with intelligent feeders can also help, this removes the potential for inserting an incorrect "dumb feeder" in the wrong slot.

Hello Spoilt... Yes it's true about the kitting being important but we also offer a component tester/verifier option for our system. The components can be tested for each insertion if you wish. The machine will not allow a component to be inserted until it passes the verification test. This feature can be used several ways. 1. test all components. 2. test all components to verify setup is correct then disable for faster throughput. 3. test only certain components on each assembly. Although our system is close to foolproof without the verifier option there are still humans involved in the setup process to potentially muck things up. The verifier option makes it foolproof. Greg
