Machine AOI

Electronics Forum | Wed May 23 08:39:37 EDT 2012 | tony_d

Thomas, We evaluated several AOI machines and narrowed the field to two, YESTech and MIRTEC. We had an opportunity to work with both of these machines on our production floor. In our experience, the MIRTEC machine simply outperformed the competitive

orientation of polarised smd components on reels/tapes

There 2 main rival standards for orientation in tape and because you can't really trust manufacturers to stick to one or the other or something else entirely it is always wise to check the datasheet. Typically an SOIC will have pin 1 the same end as

Recently, we have been having problems with PLCC's passing vision on our IP's If the part is set up to be placed on Head 2, it will not always pass vision. However, if we move it over to Head 1, it will pass and place just fine. Now, I do realiz

Yestech AOI question

We currently have two YTV-M1 inline-systems from YesTech. I have been using them for around 3 years now. They are descent machines. If you decide to go with YesTech, go for the F1 system. This will give you the ability to upgrade with side camera

I'm having a fun time between BGA rework/repair using an SRT 1000 and SPC efforts (much easier) using DEK stencil printing processes and BTU reflow with 6 Fuji lines in between. Concerning the BGA stuff, I'm getting about 60% succes

Our first pass yield across all our products is above 95% but we include anything that does not meet IPC standards. Probably 75% of our failures are not electrical. AOI is a great tool to get a consistent measure of your process. I dont know how anyo

Never had anything to do with Soltec so I cannot comment on their service. However. You must realise that machine manufacturers/distributors incur a cost in storing spare parts and making them available for immediate delivery. They are not held on co
