Made it through 156 pcs today in a marathon session. We shall see how much time I can squeeze in during the work week. The thermal printer is an amazing time saver for matching devices.

Thanks for the video!
Are boards also suitable for Dpack types (LD)?

 

[xrk971]

Actually better with the LD as you would not need to bend the pins to lie flush. Tab is connected to Drain pin 2.

 

[peppennino]

Many thanks

Great job on your automated setup !

Made me realize I have a few LR8's I might want to use in the future. Just the board without it being secured to a heatsink will be beneficial. So I'll be adding a couple more in the board GB.

 

[Bas Horneman]

I am happy to have an automated measurement and printing workflow.

Fantastic job you did there! And thanks for all the effort you've put in!

Perhaps it is time to make a spreadsheet...instead of soiling this thread with the interested in ms board?

Sorry about that. The previous link was just to view. The one below everyone can change.

Just a suggestion guys. I'm not trying to force everyone to use it. Just thought it handy.
