Calibration of SMT (Surface Mount) Assembly Machines

[shrikantborkar]

Dear All,

Recently I have been told to additional Charge for ISO Activities.

Please guide/Inform
1. How do we calibrate SMT Machines? what Parameters to be considered?
Is it been calibrate In House or M/c Manufacture can Help to this?

Please inform how you Doing this Calibration?

Thanks

Assuming SMT stands for Solder Mount Technology oven, you can't calibrate the machine as it does not measure anything. You can calibrate the thermometer used to measure the temperature in the curing stations of the machine. is this your intent of the question?

Hi, kualititaj

Thanks For your Reply.

yes , Regarging Reflow Oven , I did necessary calibration arrangement.ie. Calibtation wrt. master Temp Meter.

But My Question is regading

SMT Mounting assembly machine. where 80 to 90% population of Parts been get mounted by machine.
this part may accomodate in Maintenance activities.
I just want to confirm whether this Part will come under ISO calibration?

Please comments

Thanks

In that case, in my experience we do not claibrate an SMT mounting machine as it is not a measuring instrument, but an assembly equipment. What would be more appropropriate is to do a PM on a regualr basis and show that the pick and place head is working within specifications.

In my experience with SMT equipment, there usually is no calibration for the screen printing, pick and place and reflow oven.
Verification or preventive maintenance activities are usually conducted as per the manufacturer's maintenance manual.

Assuming you are talking about Surface Mount Techonology machines,
Some points :

For Reflow and wave machine, there’s no request for verification, due to verify the machine performance every day though the profile testing.

Primary verfication, calibration ands preventive maintainence for mounting machine ( let's say all equipment ) also comes under ISO calibration.

We do practice mounter calibration on a bi-annual basis. The area of calibration covers the following areas:

- Z-axis calibration
- X&Y axis gantry calibration
- Theta calibration
- Recognition device calibration
- Feeder truck/cart x,y,z offset calibration.

All of this is followed by CpCpK measurement.

Sine it is a CNC type of a machine you could use a ballbar, or laser to calibrate it. You might contact the bigger companys such as reinshaw and see if they have any experience.
