Material
Demands

The production methods within the electronics industry is constantly challenged by the explosive rate of miniaturisation, density and performance increases. The technical requirements on stencils for depositing solder and adhesives has increased correspondingly as manufacturing techniques advance. Stepping, high precision 20 µm apertures, µBGA, wafer bumping, aperture position accuracy whilst improving print quality and durability … 

… all rely heavily on the supporting characteristics of the base stencil material itself. 

Precision Foil 304 HTA
(1.4301)

Full hard, tension annealed 304 grade stainless steel foil meeting the highest requirements of flatness, durability and low internal stress.

Fine Structure Precision Foil 301L FS (1.4310)

Proven in the industry this unique 2 micron grain 301 grade foil offers superior smoothness of lasered or etched surfaces, minimised warping following half stepping, lowest internal stress and superior laser processing.

About Us

Penta specialises in supplying highest quality precision stainless steel foils for the demands of the surface mount technology (SMT) stencils and precision etched parts industries. All our material is sourced exclusively from the leading manufacturers in Japan. Our long established business relationships ensure consistency of supply and quality.

Availability from stock is a major part of the service Penta provides. We ship either next day or exactly as our customers request.

We supply all foils wrapped in packs (25 sheets per pack). This is convenient for not only maintaining the cleanliness of the material but also simplifies handling (and therefore avoiding damage) as well as ease of inventory control. We use robust wooden cases which can be lifted by a standard pallet truck and can be stacked 3 cases high to mimimise storage space.
