Durostone

Specifications The composite Anti-static Sheet For Wave Solder Pallets is recommended for applications where static-sensitive components.

Durostone Detailed Product Description
Durostone   Specifications Name: Durostone Sheet Color: black Thickness:3-30 mm Size: 1220x 2440mm     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.   Its flexure modulus is 20000psi. The fixture made of durostone is applicable for at least 20000 times, Compared with same kind of materials from home and abroad, our product precedes by its better quality and reasonable price.   Main Characteristic 1. Less distortion 2. Superior stability on dimension. 3. High temperature resistance.
4. Resistance to chemical corrosion. 5. High mechanical strength. 6.Good machinability (low density) and light weight. 7. Low thermal conductivity.
8. Long aplication life.   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.   Technical Data
