Durostone is a heavy-duty glass fibre reinforced plastic which offers extreme strength and excellent electrical, thermal and chemical properties. Durostone is manufactured by using Polyester, Vinyl ester, Epoxid- and modified Epoxy resins combined with glass fibers.

 

 

Durostone materials are designed and typically recommended for uses in manufacturing solder pallets for wave-solder applications of printed circuit boards (PCB's). These materials can also be used for carriers in solder paste printing, SMT placement, IR-reflow and conformal coating operations.

 

 

Name: Durostone sheet                                    :                      

Model: CATOS  

Thickness: typically 3.4.5.6.8.10.12 (mm), other thickness are available on request.

Size (mm): standard size 1220(mm) ×1020(mm), special can be made.

 

 

It can keep its mechanical strength, smoothness and original color when continuously used under the temperature of 280 degree (maximal working temperature below 385 degree 10~20s)
 

In addition, it has the advantage of easily machining, high intensity and can be easily machining into special mechanical parts.
 

Its flexure modulus is 20,000psi. The fixture made of CATOS brand synthesized stone is applicable for at least 20,000times. Compared with same kind of materials from home and abroad, our product precedes by its better quality and reasonable price.
 

The product of 3mm can be used for reflow process while other domestic products do not have the advantage.

 

Protect the SMT components in the back of the PCB board during the wave soldering process
 

Carry an irregular shape baseboard
 

Use multi-pak panel design to improve production efficiency
 

Prevent the deformation of the baseboard during high temperature reflow process
 

Smooth surface, patience high, can be applied to spray Teflon (Teflon) process
 

Avoid gold finger contamination by human contact
 

Protect the SMT components in the back of the PCB board during the wave soldering process
 

Prevent the deformation of the baseboard during the wave soldering process
 

Standardized the width of the production lines, eliminate the width adjustment of the production line
 

Use multi-park panel design to improve production efficiency
 

Prevent the surface of the baseboard from overflow tin contamination
