Lead-free material made in china

Item :  NS503- black lead free material

 

Product Description

NS503-Black Lead-free material is a kind of insulation sheet for wave solder pallets, It is as same as Durostone and Ricocel sheet. It is the top grades of the material made by glass fabric and epoxy resin, it is a lead-free material Designed for who wanted to enhance productivity and reduce the loss of the products. This item can withstand the temperature more than 380 degrees (10~20seconds). And keep its mechanical strength, smoothness, and original color when continuously used during the temperature of 300°c.Composite materials Lead-free material is another kindly of excellent material for SMT fixture & carrier, wave solder pallet, reflow soldering, SMT oven tray, had tin furnace jigs, such as PCB and electronic industry

Product Features

Product Uses

There is exclusive access for customers to a range of technical support materials that will help improve solder pallet design, lifespan and, ultimately, the quality of the PCB.

Wave solder pallet design is important to avoid soldering defects such as solder bridges or shorts, inadequate hole fill, solder splatter and solder flooding the PCB.
The lifespan of solder pallets depends on many factors including material choice, pallet design, and process conditions. This site contains answers to many of the issues faced by the PCB assembly industry today.

We have different grades insulation material which is suitable for use in the PCB reflow and wave soldering processes, NS503, NS306, NS302 and NS301 This site is a technical resource for all aspects of solder pallet materials, from the base material to the quality of the soldered PCB, Wave solder pallet design is important to avoid soldering defects such as, solder bridges or shorts, inadequate hole fill, solder splatter and solder flooding the PCBN
