Just recently installed new machine with Hawkeye 400, the vision system is extremely easy to set up and run. We have only been running but 6 weeks, but I would recommend the system versus the cost of a inline solder paste inspection systems. If you i

Watch the solder profiles allowed for these caps. Most electrolytics cannot withstand high heat. Even RoHS compliant Electrolytics are often rated for peak 245C, 3 secs max, for example. Nowhere close to the 260C 10-20 sec you usually like to see.

We do something quite simple that may or may not be adequate but I cannot think of why it would not be adequate. If anybody can please inform. We have a large board about the samer width as our oven. We have dedicated thermocouples on this board a

Pardon me for being so bold, but I still cannot understand to this day why solder paste thawing is an issue. I am not sure what types of paste you all are using but it has been my experience that the only thing you gain by refrigerating is 3 months

Step stencils are not widely used, due to: * Higher cost as compared to uniform thickness stencils * Danger of solder paste smearing at least close to the steps * Difficulty of cleaning the stepped stencil underside (the steps cannot be on the upper

Thank you very much. I swapped the component length and width measurements in Autoprogram and it now places the SOT23's with image verification no problem. As for the 0402's I am still working on this. Pick and place is very new to me, well I start

I unfortunately cannot post any photos, the unit in question is classified. And, as far as my comment that the BGA profile can be manipulated, if an engineer is also working the process with one of the operators, they can override the profile at any

Sometimes you gotta do what you gotta do! We have to perform this on occasion as well. We perform this when we cannot get a board to stay free of tacoing, oilcanning, sagging or warping. (we needed a bigger preheater dimension wise) We have one no

8.2.5.5 Flat Ribbon, L, and Gull Wing Leads, Maximum Heel Fillet Height (E). For class 3 the heel fillet cannot touch the body of a plastic component, except for SOICs and SOTs. Why is my question? What type of failure will be the result of solder

Hi John, Are you talking about cleaning the pallets after running to store them? or during production? well in any case...I recently started to use this cleaning solution "Cybersolv" from Kyzen. It is water soluble and also can be used instead of IP
