I. Description
Durostone is a heavy-duty glass fiber reinforced plastic which
offers extreme strength and excellent electrical, thermal and
chemical properties. It can keep its mechanical strength,
smoothness and original color when continuously used under the
temperature of 280°C (max. working temperature below 385 degree 10~20sec).
In addition, durostone have the advantage of easily machining, high
intensity and can be easily machining into special mechanical
parts.
II. Main Characteristic
1. Normal working temperature at 325 °C, operating temperature up
to 384 °C
2. Less distortion, low thermal conductivity
3. Superior dimensional stability, Long life
4. High temperature resistance
5. Resistance to chemical corrosion
6. High mechanical strength
7. Good machinability (low density)
III. Application
Functions:
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
Benefits
1. Wave Solder Pallets provide strong, stable support for the PCB
throughout the wave solder process
2. Wave Solder Pallets permit wave solder processing of
through-hole components while masking solder-side SMT components
and critical board features from molten solder
3. Wave Solder Pallets provide thermal protection for printed
circuit board areas that are heat sensitive
4. Wave Solder Pallets allow processing of odd-shaped PCB's through
conveyor system
5. Wave Solder Pallets prevent topside component movement
throughout wave solder
6. Wave Solder Pallets align and position topside components
throughout wave solder
7. Wave Solder Pallets increase assembly production by eliminating
hand gluing and masking operations
8. Wave Solder Pallets ensure higher quality, repeatable process
results
9. Wave Solder Pallets reduce bridging and skipping solder defects
10. Wave Solder Pallets provide safe, easy, ergonomic handling of
PCB

Working your way around the underside of the PCB, identify which
components
are parallel and perpendicular to the wave and assess the
solderability of each
PTH connector by comparing the actual separation against the graph
right.
Ideally you want to be above the line in all cases.
