Wave Solder Pallets ESD Synthetic Stone Safe Composite Materials

Wave Solder Pallets ESD Synthetic Stone Safe Composite Materials

Universal/ Adjustable Wave Solder Jigs with Double Slots

【Description】

Designed by engineers with extensive wave solder experience, our pallets enable customers to automate the soldering of through-hole components on complex electronic assemblies.

The pallets only expose areas of the assembly that require soldering. All other areas are protected, eliminating component damage and expensive, low quality process steps. Made of ESD-safe composite materials, these pallets are designed and manufactured to optimize both the solderability of your circuit boards and your entire process flow.

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 

This estimation may be done in three ways

If a PCB is available (preferably populated) - our sales engineers can rapidly evaluate your board. 
If PCB design data is available we will process, analyse and remotely assess it. 
You can do it using the rules presented below - our customers quickly find that the above two methods are easiest.

Gerber, Excellon and other data required 

Pin Land to SMT pad clearance evaluation

The two figures below each show part of a CSWSC in plan and section views. The right hand figure shows that more clearance
is required when the connector orientation is perpendicular to the wave.

Working your way around the underside of the PCB, identify which components 
are parallel and perpendicular to the wave and assess the solderability of each 
PTH connector by comparing the actual separation against the graph right.

Ideally you want to be above the line in all cases.

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.
