Anyone has experience with Humiseal 1B31LOC and 1B31? Their material properties(physical, chemical, temp. etc) are fairly much the same after cure but there are some differences when they are at liquid stage. We are currently using 1B31 but is planni

Low Air Pressure: System reporting low air pressure; verified 12Vdc at pneumatic panel, manually jumpered and verified connections back to GPIO1 connector on the LOC I/O assembly. Swapped LOC IO cards then entire LOC IO chassis, with another machine.

We're using the 1B73LOC conformal coating from Humiseal. We've seen some bubbling of the coating. Their tech handbook suggested reducing our oven ramp speed. Does anyone have a good profile for this? They've always pointed me to Nordson, and Nord

You need to get your local rep to demo the grid loc. That is what it is for double sided boards. when the table comes up the pins adjust to the different height components. I also thought I saw a similar product on one of the advertising Panes on thi

With the UP2000 that has vacuum board hold down, the Grid Loc hoses defeat the vacuum in order for them to exit the work table. Big boards require more girds, thus more hoses. Set-up between large and small boards takes time to remove or add the gr

As for the bubbles/fisheyes, try increasing your thinner ratio. This sounds like your coating is thickening up before you are able to apply it to your application.

Thanks all for the input. We've been to both DEK and MpM for demos and seen the grid-loc in action. Think we'll probably go with that along with our h-towers and dedicated tooling.
