CDM [FRP Materials]

PCB Solder Pallet Material Selector ,Polyimide resin matrix composite.

CDM materials have superior mechanical properties and dimensional stability at elevated temperatures, such as those used in the lead-free soldering process. The material was developed to allow solder pallet designers create the best solutions for the PCB assembly industry. 
CDM stone is a high quality solder pallet material that enables good pallet design providing the best possible results from  the wave soldering process.
The lifespan of solder pallets depends on many factors including material choice, pallet design and process conditions.
