The only material I've ever heard of for these applications is the one that you have already rejected (Durostone). There is a similar material called Durapol, and if memory serves me correctly it is somewhat cheaper than Durostone.

Thank you. Maybe I'll just order some oversized thick boards from the board house with no traces. There has to be a lower cost way than paying that kind of money they are asking for those products.

How wide is this board? I ask because if it's not terribly wide, you might just be better off attacking the problem with the profile rather than attacking the board conveyor design.

BGA and QFP orientation in trays for pick and place

BGAs and QFPs packaged in Trays are oriented with Pin 1 or corner A1 oriented towards the Pin 1 identifier on one corner of the Tray, which is usually identified by a chamfered corner. The Trays themselves are usually governed by JEDEC Registered Ou

First thing we did was visit the profile and we have it adjusted as far as we're willing to take it. I'm just going to make a carrier design in cad and have the board house produce some in their thickest substrate to see how it works out. Thanks.

We just use scrap PCBs for Oven carriers. You could probably contact your board house and as for just sheets of FR4 to use. I've also used a binder clip at each corner to lift a board off of the mesh belt in a pinch.

A couple of caveats; The FR4 will degrade with successive reflows and will eventually need to be replaced. Not a big deal for low volume, but something to be aware of. The bigger concern is that a sheet of .125" large enough to position your assembl

Thank you Clare. After doing some more research, I found they are known in the industry as "Carriers". I did look into that durostone material. They prices are beyond reasonable. My trek now is seeking a material to make planks out of to lay the b

Hello! Don, Yes, if the carrier is steel/stainless, it would be very hot when it comes out from oven. I heard that durostone (synthetic stone) carrier can meet your requirement, it can stand high temperature with low thermal transmission. So when it
