Black Durostone Sheet for PCB Wave Solder Pallet

I.  Description

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

It can keep it's mechanical strength,smoothness and original color when continuously used under the temperature of 280°c (max. working temperature below 385 degree 10~20sec). It's applicable in ROHS applicance production line under high temperature continuously.

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

II. Main Characteristic

10. A certified anti-static material, anti-static index ups to 10^5-10^9 per square

 

II.   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.
