SMT stencil standard: measure the four corners and the middle, target value is 26N/CM or more

Hi all, I have a GRUNIG G-CHECK tension measurement tool, I need to prepare a calibration report internally. https://graphcom.gr/product.php?lang=en&id=128 Measuring range between 7 and 50 N/cm Thanks for sharing any useful calibration instruction

I was consulting the manual of the machine and to measure the tension of the x belt I need a frequency counter and two prisms but I don't have these tools, is there any other way to measure the tension?

Hi ALL, Please confirm what measuring instrument do you use on stencil measurement. may we know the brand and website of this instrument.? We also need to measure the sencil tension but we do not have the instrument. Thank you, Arman

We assume by "stencil tension" you mean a measurement of how securely [or how tauntly] the stencil foil is held in the stencil frame. If so, we do not know how you would go about making your "30 ~ 50 N/cm" limit measurement when verifying conformanc

Yes, we have an SOP on how to measure. Basically, calibrate the measuring device and measure tension on the 4 sides and one at the center of the stencil. All measurement should be within 30 ~ 50 N/cm otherwise we will not use it and return it to sten

Davef, Thank you for your reply.You are right that I need to consider the tickness also of the stencil. Previously, I take for granted this process of measuring the tension and I usually let my technician do that. However, I have to determine the pra

There's a lot of parameters to consider in defining stencil life cycle. Average squeegee pressure used, in-process cleaning frequency (auto and manual), physical appearance over time, tension reading over time, and so on to decide how many print cycl

Evtimov , i agree with Thomas.. you don't have to take your mesure in the middle of the stencil since the sheet of the stencil has the same thickness everywhere either in the corners or in the middle.. So you can ask from your stencil supplier to mak

Thank you for your reply Djo. What do you consider a normal range tension for 29" stencil on a hard frame? Also I am not sure how I can use micrometer in the middle of 29" stencil to measure the thickness? CAn you please clarify?
