The experimental way is the best approach for SPI settings and fine tuning. Have a start point of +/- 20%. You build 0402s and machine flags them 35% offset from value. You reflow, perform AOI - everything is fine. You go back and you move tolerance

Hi All, Could you share for me inspection spec that you set up for SPI machine ? Which standard you base that? IPC or something like that. So far, my factory set up as below: Area , volume , high are: lower limit is 60%, upper limit 160% for 0201 ch

Has anyone ever created a validation process for their SPI? I recently took over the programming of our Kohyoung spi's and was asked how do I know the settings I set are correct. The only answer I had was visual inspection under a scope and the set

SP1 is a bi-metal spring loaded switch or the "air fault" switch on the main air manifold that detects the presence of an appreciate amount of air being supplied to the machine. Air pressure overcomes the adjustable spring and closes the contacts.

My product has 2.4Mil and 3.1Mil stencil. For both the stencil my SPI specification is set as 30% to 160% How this is calculated. Can anyone enlight me. Solder Paste type 5. Minimum opening is 0.16*0.18mm in stencil.

Diego, the first question you have to answer is "Is the paste volume too much in real?" How does your paste look? To check that, I would say you measure bare board with your SPI and see if your SMT pads show you zero, or may be not? If your value fo

Thank for your sharing. I am also trying find out the best parameter for our product.

Hello sir, Limits in SPI can vary a lot, also depending on finishing of the pcb. For example 170% volume on an IC (assuming is fine pitch) can be okay for ENIG, but very bad if HASL. For are I would recommend that you use either 50-130, or 60-135 max
