I.   Description

Synthetic stone is a glass fiber and high temperature,high mechanical strength sintered resin.Colors are black,blue,grey(reflective type).The company is the synthesis of stone products in the domestic first successful development and mechanized production enterprise.

II. Main Characteristic

1. Less distortion

2. Superior dimensional stability.

3. High temperature resistance4. Resistance to chemical corrosion

5. High mechanical strength.

6.Good machinability (low density)

7. Low thermal conductivity8. Light weight

9. Long life

III.Application

Durostone is suitable to wave soldering and SMT process. It can achieve the precision required during the SMT machining process, and maintain its flatness in the reflow soldering cycle. The low thermal conductivity of the durostone prevents heat-shrinkage of the bas board, to ensure the quality of reflow process.

The fixtures made from durostone has the following functions, it can improve the efficiency of the peak soldering process:

1.      Support thin baseboard or soft substrate circuit board

2.      Carry an irregular shape solder pallet.

3.      Use multi-pak panel design to improve production efficiency

4.      Prevent the deformation of the solder pallet during high temperature reflow soldering process

5.      Smoothly surface, good endurance, applicable for Teflon spray painting.

6.      Avoid gold finger contamination by human contact.

7.      Protect bottom side SMT components during the wave soldering process.

8.      Prevent the deformation of the baseboard during the wave soldering process

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

10.  Prevent baseboard being contaminated by the overflow of tin.
