TO package options

EPIGAP OSA Photonics offers a comprehensive Photonic Assembly service covering the full packaging workflow for optoelectronic components, from individual chip placement to completed hermetically sealed modules. The service supports a wide range of package formats including custom SMD layouts, TO-cans, Chip-on-Board (CoB) assemblies, and multichip modules, with placement accuracy down to +/-10 µm and multichip assemblies integrating 20 or more components per module. All assembly work is performed in-house at the Berlin Kopenick facility under controlled conditions, with complete lot traceability.

The assembly service is structured around five core capabilities: chip bonding and pick-and-place, gold wire bonding, encapsulation, TO packaging, and SMD packaging. Wire bonding uses gold wire from 17 to 30 µm diameter with ball-wedge and wedge-wedge techniques, qualified by pull and shear testing to MIL standards. Encapsulation options span flat, dam-and-fill, glob top, and lensed formats in clear, white, or light-blocking black materials, with phosphor conversion coatings available for white LED or NIR emission applications. Hermetic TO-cans are assembled under nitrogen or trimix atmosphere, with optional thermoelectric cooling (TEC) integration and custom optical caps including AR coatings and bandpass filters.

This service is especially suited to OEM customers in medical technology and biophotonics, industrial sensor and automation, and safety and security segments who need small-to-medium production series with tight spectral and binning specifications, serialized documentation, and complete supply chain management. EPIGAP OSA handles everything from prototype to series production, including burn-in, qualification, tape-and-reel delivery, and failure analysis.

What package formats does EPIGAP OSA support for photonic assemblies?

EPIGAP OSA supports a broad range of package formats including SMD (FR4, PLCC, ceramics), TO-cans (TO-46, TO-18, TO-39, TO-5, TO-3), Chip-on-Board (CoB), and fully custom multichip modules. Substrates can be FR4, flex PCB, IMS (Insulated Metal Substrate), ceramics, or TO platforms.

What die attach and chip bonding methods are available?

Available die attach methods include flip-chip, Chip on Submount (CoS), eutectic soldering with AuSn preforms or Sn-Ag-Cu alloys, and vacuum soldering at both low and high temperatures. Placement accuracy is down to +-10 µm, and both manual and automatic die attach are offered.

What wire bonding specifications are supported?

EPIGAP OSA uses gold wire in 17, 25, and 30 µm diameters with ball-wedge and wedge-wedge bonding modes. Advanced bumping techniques including Bond Stitch On Ball (BSOB) and Safe Bump are available. Bond quality is verified by pull and shear testing per MIL standards.

Can TO-cans be assembled with custom optical caps or cooling elements?

Yes. TO-cans (TO-46, TO-18, TO-39, TO-5, TO-3) can be fitted with custom caps including lenses, flat windows, AR-coated windows, and bandpass optical filters. Assembly is performed under inert or dry atmosphere (nitrogen or trimix), and optional thermoelectric cooling (TEC) can be integrated.

What wavelength range and conversion options are available for encapsulation?

Encapsulation materials cover the full spectral range from UV to SWIR. Options include clear, white, and light-blocking black materials. Phosphor conversion materials are available for white LED or custom NIR emission targets. Bandpass and AR coating optical elements can be integrated into glass caps.

What is the typical production volume range and traceability capability?

EPIGAP OSA handles small to medium production series - from prototype batches to several million SMD components per run. Full wafer-level traceability is maintained for all proprietary chips. Serialized documentation with individual measurement reports per module is available on request, along with burn-in, qualification, and supply chain management services.
