BEST can laser drill slots, grooves, and holes of any shape into many of the specialized polymers and metals used in the electronics industry. The BEST laser drilling process has produced holes as small as 30um in Polyimide, Polyester, and copper for its customers in the flex-circuit industry. The holes BEST drills are free of burrs, lips, melting, flashing, and burning as the material is evaporated or ablated away. The precise control of the energy, the time pulse of energy and the amount of energy allows for precision laser hole drilling.
Our laser hole drilling capabilities allows BEST to drill holes in flat panel glass displays, various flex circuit materials as vias as well as vias and blind vias in FR-4. Furthermore holes are cabn be drilled in cover layers for flex circuits as well as holes in copper, gold, silver and other metals used in the electronics industry,
The precise location of the holes as well as the repeatability of very small (30 microns or less) holes makes the laser drilling of holes a precision event. Holes can be drilled in locations determined by the fiducials on the printed circuit board or flex board or via tooling and the dxf file locations. We can take in a variety of drawing electronic file formats in order to make it easy to interface with our laser drilling department.
BEST can also laser drill holes and other patterns in a variety of surfaces including glass, ceramic, metals and polymers. This versatility of the laser sources at BEST along with our experience in drilling millions of micro holes in various polymers every year makes us well-suited to be your services supplier for various value-added OEM products.
Examples of materials:
- Polyurethanes: Flex Circuit Micro-Vias
- Teflons: Insulating Parts
- Polyimides: Flex materials, Insulators, Stencils
- Copper: Specialty Spacers, Trace Patterns
- Stainless Steel: Stencils, Squeegees
CAD system integration and custom file converters enable flexible, laser manufacturing from user-provided data. Although most file types are accepted, the preferred file types are Gerber, DXF, or other 2D formats. In most cases, non-scaled data is required as BEST technicians will make the appropriate offsets and properly scale in order to meet part dimensions.
