Durostone Solder Pallets for Component Bake Out Storage Shipping

Benefits

1. Machined with custom pocket dimensions for safe handling and package protection
2. Allows Surface Mount components to be picked up in a repeatable fashion when tape and reel is not an option
3. Provides pick and place SMT package presentation solution for components for which no standard JEDEC tray exists
4. Useful for component bake-out, storage and shipping

Features

1. ESD safe composite material
2. Pocket can be designed to handle many different package styles including QFP, FP, BGA, LGA, CGA, etc.
3. Fast turn times

Features

1. Maximum possible "Knife Edge" beveling of fixture openings, provides the best possible solder flow to component leads View Image
2. Wave Pockets and Solder Channels promote better solder flow View Image
3. Ergonomic PCB and component holddowns. View Page - Holddowns
4. Pallet design keeps bottom of circuit board coplanar with the conveyor
5. ESD composite construction protects sensitive components by providing controlled static discharge
6. Free PCB pocket covers provided with multi-up fixtures

Other advantages are:

1 Eliminate flooding by masking open areas and preventing board sag.
2 Reduce second hand load parts and hand soldering.
3 Save thousands of dollars in Kapton tape and the labor to add and remove.
4 The composite materials thermally protect bottom side SMD’s from shock.
5 Mask BGA vias from the wave ensuring reliable solder joints.
6 Lead Free grade optical material for higher temperatures

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.

Why choose us

PCB Design Implications - for Board Designers - or respin

We are often called upon by our customers to help with identifying design respin opportunities.

We will identify problem areas within a board and suggest appropriate movements of components. (Ideally before the PCB is fabricated)

However for board designers reading this, can you remember another four "rules" (to compete with the hundred other rules you have to have floating
around in your head).

Keep large (height) SMT components away from PTH areas.
Leave the leading and trailing areas around PTH components as clear as possible.
DON'T put any SMT components within 3mm (0.12") of any PTH components.
DON'T put all PTH components in line along one edge of a board - leave some space to allow us to support the masking in the centre of the board.
