Product Description
Solder pallet material are composite material made of glass fiber and epoxy resin. In the indirect high temperature environment of 260-280ºC, it has good dimensional stability, corrosion resistance, low thermal conductivity, anti-static and non-flammability. Suitable for soldering protection in SMT wave soldering process, easy to process, no cracking, no peeling, no burr and no irritation to human body. Easy to process on CNC lathe and do less harm to the cutters. We have the unique automatic production line in China, therefore steady production can be assured, that can also avoid problems like porosity, transformation and layer separation. All these problems are easily seen in handmade production.
These materials offer the following features:
(1) Corrosion Resistance: Based on our own intellectual property and R&D Capability.Our composite sheets have great advantage over that of other domestic producers. The carrier life has been prolonged effectively.
(2) Less Burr after machining, not easy to be separated and break on the processing position.
(3) Uniform ESD, No porosity, No impurity,Uniform fiber distribution.
Description
Durostone is a fiber-reinforced plastic for mechanical and electrical applications. With good performance against electric arc and tracking, it is an ideal material for solder paste printing, SMT process, reflow soldering and wave soldering.
Characteristics
-Good Anti-static property
-High strength and good machinability
-High temperature resistance
-Tight machining tolerance
-Chemical resistant
-Long life cycle
Durostone's function in PCB assembly
1. Avoid pollution due to human contact
2. Reduce disposal rate
3. Prevent PCB from bending
4. Standardize the width of production line
5. Impove producion capacity by using muti-functional fixtures
6. Cover the SMT parts at bottom, make the partial welding available
Durostone's function in wave soldering
It can keep its physical properties at increasing high temperatures. So it can reach high precision without any deformation. There are no layering, bubbles, deformation when working at 380 ° C for a short time.
We can also design pallets as per client's requirement. Below information are necessary for the pallet design.
1. 2D drawing(.dwg or PDF) or 3D drawing(.STEPor .IGS) of wave solder pallets
2. Gerber file of PCB bare board+ Loaded PCB sample(PCB board with electronic components)
