Alpha 锡膏OM340EN规格书英文版(2)

APPLICATION

Formulated for both standard and fine pitch stencil printing, at print speeds of between 25mm/sec (1”/sec) and 150mm/sec (6”/sec), with stencil thickness of 100μm (4 mil) to 150μm (6 mil), particularly when used with ALPHA® Stencils. Blade pressures should be 0.18-0.27 kg/cm of blade (1.0 -1.5 Ibs/inch), depending upon the print speed. The higher the print speed employed, the higher the blade pressure that is required. The reflow process window will give high soldering yield with good cosmetics and minimized rework.

SAFETY

While the ALPHA OM-340 flux system is not considered toxic, its use in typical reflow will generate a small amount of reaction and decomposition vapors. These vapors should be adequately exhausted from the work area. Consult the most recent MSDS (available at ) for additional safety information.

STORAGE

ALPHA OM-340 should be stored in a refrigerator upon receipt at 0 to 10°C (32-50°F). ALPHA OM-340 should be permitted to reach room temperature before unsealing its package prior to use (see handling procedures on page 3). This will prevent moisture condensation build up in the solder paste.
