PCB Pallet Matrix Trays Selective 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
Fabrication Drawing
Drill Fab Layer
Other Requirements:
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

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.
