How to choose the good wave solder pallet material for PCB soldering

To choose the good wave solder pallet material usually need consider following facts. 1. Good flatness and strength 2. Easy to machining, not hurt the cutters 3. Can work under high temperature at least 260 centi-degrees for long time 4. Repeat work times not less than 10000 6. Lead-free 7. Made by heavy automatic hydraulic stamping press machines Energetic Industry wave solder pallet material give flatness at ±0.10mm, compressive strength ≥ 340~510 Mpa, easy for machining, long time work temperature ≥280 centi-degrees, max short work temperature 410 centi-degrees, 12000 work times, 100% lead free, Rohs approved, 3500 tons automatic hydraulic stamping press machines made. Stock Color: Black, grey for customized Thickness: 2mm ~ 50mm Size: 1020mmx1220mm, 1220mmx2440mm More information please visit our web site and email us.

Nylon and UHMWPE’s properties comparison

Both materials are come with good wear-resistant, but the wear resistance of UHMWPE is about 3 times of nylon, and the tensile strength is much better than nylon too. The hardness of nylon is better than that of UHMWPE. In addition, the impact resistance and freezing resistance of UHMWPE are better than nylon. Nylon material has poor water resistance. No comparison with super high materials. If work environment have water or moist , it is recommended to use UHMW sheet to make plastic gear , plastic rollers, plastic liners.

Bakelite Sheets

Stock Color: Black, Orange Thickness: 3mm ~ 100mm Size: 1020mmx2020mm Lead time: 3 ~ 5 days - Other sizes  can be cutted, colors according to required application. - A grade quality ordinary bakelite, Black ESD bakelite About Bakelite Sheet : Phenolics are a uniformly dense and structurally strong material that will not soften appreciably under the reapplication of heat. It is an extremely durable plastic that is lightweight and moisture resistant. Industrial laminates are thermoset resin impregnated reinforcing materials (paper, cotton fabric, glass fabric, etc.) that are cured under heat and pressure to form solid shapes having high mechanical and electrical insulating properties. Laminates are available in sheet, rod, and tubes. Since laminates are comprised of a combination of materials, they are also referred to as composites. Advantages : High mechanical properties, and oil resistance and certain dielectric property. Thermal rating 120 grade, and temperatur
