LORD 8621

Main features

  • Screen-Printable Resistor Paste
  • 90 to 110 Ohms/Square
  • 14 to 18 Micron Film

Product Description

LORD 8621 Polymer Resistor Composition is a legacy screen-printable black paste within the LORD 8600 Series for creating polymer resistor features on thermally compatible substrates. It has a typical viscosity of 20 to 40 Kcps at 25 deg C and a cured sheet resistivity of 90 to 110 ohms/square under the stated alumina, cure and test geometry. The printed-film thickness is 14 to 18 microns. Supported application substrates include printed circuit boards, ceramics, glass, phenolic materials and flexible substrates capable of withstanding the required thermal processing. Current availability, lifecycle status and exact product SDS coverage require confirmation.

Key features

  • Screen-printable resistor paste: Designed to create polymer resistor features through a controlled printing and thermal-processing sequence.
  • Legacy cured resistivity range: Has 90 to 110 ohms/square after cure under the specified alumina and geometry conditions.
  • Multiple supported substrates: Can be used on printed circuit boards, ceramics, glass, phenolic and suitable flexible substrates.

Applications

Applications include screen printing resistor compositions onto printed circuit boards, ceramics, glass, phenolic and thermally compatible flexible substrates.

Physical Properties
Viscosity
Viscosity is a measurement of a fluid’s resistance to flow. Viscosity is commonly measured in centiPoise (cP). One cP is defined as the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP. A product like honey would have a much higher viscosity -around 10,000 cPs- compared to water. As a result, honey would flow much slower out of a tipped glass than water would. The viscosity of a material can be decreased with an increase in temperature in order to better suit an application
20000-40000 mPa.s
