Material Composition
Synthetic glass fibre reinforced resin sheets provide the physical structure for ricocel tooling during automated soldering operations. These boards withstand extreme thermal cycles common in reflow ovens and selective wave soldering machines without warping or losing dimensional accuracy. Resin composites of this type maintain electrical insulation properties even when exposed to high flux concentrations and repeated heat exposure.
Engineers select this material when copper clad laminates require stabilization during the passage through molten alloy baths.
Process Utility
Wave solder pallets rely on ricocel tooling to protect non-soldered regions of the printed circuit board from direct contact with molten metal. Holes machined into the fixture match the specific footprint of bottom-side components, permitting the alloy to reach intended pads while shielding sensitive connectors or thermal-sensitive packages. Each fixture must align precisely with the conveyor system to ensure repetitive positioning throughout long production runs.
Thermal expansion coefficients of the material remain close to the substrates it supports, preventing mechanical stress on solder joints during the cooling phase.
Failure Prevention
Dimensional stability defines the operational lifespan of the fixture in high-volume assembly lines. Over time, recurring contact with acidic flux residues and thermal cycling causes the resin to degrade, leading to uneven boards or poor solder fillet formation. Technicians inspect these tools for cracks near thin wall sections where physical fragility increases due to repeated heat shock.
Regular maintenance protocols mandate the replacement of fixtures once surface pitting exceeds specified flatness tolerances. Wear patterns on the bottom side of the pallet provide early warning signals regarding alignment drift in the transport system. Accurate fixture geometry determines the consistency of solder joint quality across an entire production lot.
