Selective PCB Pallet Matrix Trays Wave Soldering Pallets 1.85g / Mm3
We recommend to use Reflow Pallets of Durostone Material, for your different PCB shapes, thin PCB material use to avoid warpages on your assembled board. You will be able to work effective with every kind of shapes and material thicknesses.
The following are the general data files required for fixture development. Products are processed differently. Supplying us with all of this data will ensure that we have what is needed for your application.
Top & Bottom Side Silkscreen
Top & Bottom Side Paste
Top & Bottom Side Mask
Drill Fab Layer
Height of components on the solder side of the PCB
Height of components requiring hold downs
Identify any components which overhang the board and whether they seat flush to the top of the PCB or receed to a certain depth
|Maximum Operation Temperature(C)||350||350||350|
|Tickness/weight(mm/kg)||3/17, 4/22||5/28, 6/33, 8/44||10/55, 12/66|
TOP SIDE STANDARD FEATURES
Chuangwei’s standard PCB hold down is our low profile. It is unbreakable, ESD safe and guaranteed for the life of the pallet. The non-marring design applies 12 pounds of downward pressure without having to lift. Just twist! We also offer a high profile hold down, cam-lock and custom hold downs for connectors.
Chuangwei does not ‘tap’ the composite, we use all “metal to metal” fasteners ensuring a reliable and long lasting fixture.
We offer two sizes of extruded aluminum stiffeners and solder dams; for smaller pallets we have a 3/8” tall and for larger pallets we have a 3/4” tall design.
All pallets are engraved with the board name and our work order number for handy reference. All data associated with your pallet is stored to that work order number.
BOTTOM SIDE STANDARD FEATURES
All bottom side fasteners are made from 316 grade stainless steel. This eliminates solder sticking or wetting to the fastener.
All fasteners are thread locked.
Our goal is to design and build a solution that will give you:
1. Highest yields with the largest process window possible.
2. Easy to use tooling that will survive your manufacturing environment.
3. Fastest delivery times possible.
