1. Verify all the part had load to machine. Get ready for the profile. 2. Run the board with double side tape. Is better to run one board for each machine. 3. Verify all the placement ( missing, misalgnment,etc )and check the value using meter for a

You have given little detail for anyone to help. What types of components are laying in the machine? Are these components missing from the PCB? But you can check these things. 1. Check vacuum at nozzles 2. Check for obstructions in the path of the

There are a couple of things that I would check. Check the board clamps and make sure that they're in good shape and that they're actually holding the board securely. If those check out I would take a look at the fid camera and make sure that every

Hi, as far as I remember Juki machines have sendor to check if there is a feeder high. So you have several thingd to check here: 1. Check if there is a feeder high 2. check the sensor calibration. I think it is a beam from one side that goes streig

Hello, This is from my old documents....hope it helps. I would first try mod code 53 = 2 first.....if the machine is a 2C. The motor was known for causing this problem after getting old. These are all resolutions for motor error 4. Step Potential P

Hi Mefunak, I'd say that the vacuum holding circuit is at fault. If the component is picked OK from the feeder ('vacuum check after pickup' is switched on) then the component is being dropped from the head as the gantry moves to the placement positi

thank you for taking the time to look at this post. hopefully someone can help. I have a GSM2 Q block with a Flexjet 7 spindle head. a couple of days ago the machine encounter this issue while zeroing. the issue is with head 2 on beam 2. on the di

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

There is three ways to make sure that the component you are about to place is on the correct feeder: 1 Check for the proper component and for the proper feeder location. 2 Check for the proper component and for the proper feeder location. 3 Check for

If you are certain that reflow process is good, I would suggest starting checking the following: 1. Check to see if leads / pads are contaminated or oxidized. However, this usually results poor solder quality throughout the board. 2. Check the amou
