PCBA is a data driven business, if BOM and CAD are merged correctly and signed off as correct, then correct smt programs can be generated etc - the correct software tools can help drastically here. I think get it right first time is better than spen

Just to be use that we're heading in the correct direction, you're probing solder, not copper, correct?

First thing to check is that you have a good gasket between the PCB and the stencil (if not check that the tactile is free of paste at the base of it and calibrate the tactile. I am assuming it is not a head mounted tactile) Also check that the wipe

Does anyone know how often the optical sensor goes bad on the CS-400E machines. I have 2 machines and it seems that the optical correction does not work anymore. I keep getting an optical correction error, when the mode is turned on the correction

thanks I haven't the same shift in all the components, that's why I need to correct them one by one and this takes a lot of time. I am searching in the Software of the machine if there is any way to change just one parameter to correct all the data

Yes, you are correct, no fiducial correction. If I force a fiducial correction, then the placement is alright. I should also mention that the placement gets worse as the production continues. I checked the lead screws and bearing holder...looks o

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 moun

If the connection is poor you would need to consider was the solder volume correct & is the oven profile correct? Was the paste mixed correctly & within all operating windows such as exp date, time out etc etc

We have a system where when we set up the line to run a job before the first part is placed an auditor verifies we have all the correct parts loaded on the machines in thier correct locations. We then run a first article. The board is inspected to in

Check flux penetration and type of flux. How much is solid contents. The solder filling is better under Nitrogen. Check the time (speed) of the nozzle whether is correct. Usually For SAC305 the temperature of bath is 320C/degrees, but only for sel
