Die Bonding Companies

Last updated: January 2026

This directory lists 61 die bonding companies across the United States, from highly specialized R&D-focused facilities handling intricate MEMS and photonics to high-volume automated assembly houses adept at power electronics and automotive modules.

Buyers typically engage these companies to solve complex packaging challenges, such as achieving extremely tight bondline thickness for advanced sensor arrays, ensuring low voiding percentages for high-power devices to prevent thermal hotspots, or precisely aligning multiple die for 3D integrated circuits. These capabilities are crucial for meeting stringent reliability targets and optimizing device performance.

Suppliers in this space vary significantly, ranging from boutique service providers specializing in low-volume, high-mix prototypes requiring extensive engineering support, to large contract manufacturers offering full turnkey assembly with dedicated production lines for specific technologies like flip chip bonding or advanced multichip modules. Some focus on specific markets (e.g., medical, mil-aero), while others offer broader capabilities.

To ensure a successful engagement, buyers should come prepared with detailed schematics, die-level material specifications, target environmental conditions, and clearly defined electrical and thermal performance requirements. Suppliers, in turn, will expect to see preliminary designs for manufacturability (DFM) feedback and clear acceptance criteria, including specifics for post-bond inspection and testing.

How to Choose a Company

  • Validate their pick-and-place accuracy: For micro-sized die (e.g., <200µm), confirm the supplier's equipment can consistently achieve placement accuracy of +/- 5µm or better, backed by statistical process control (SPC) data for their production lines, especially if working with high-density arrays or flip chip designs.
  • Assess their post-bond inspection capabilities: Demand evidence of in-house non-destructive inspection methods like X-ray for voiding analysis and Scanning Acoustic Microscopy (SAM) for delamination, along with destructive tests such as die shear strength and wire pull testing, all with traceable calibration records.
  • Confirm expertise in your required die attach method: If your application demands high thermal conductivity or extreme reliability, verify their specific experience and successful case studies with eutectic bonding or silver sintering, rather than just epoxy die attach, including their ability to control reflow profiles and atmospheric conditions.
  • For medical or aerospace applications, require specific certifications: For medical implants or critical diagnostic tools, insist on ISO 13485 certification. For aerospace or defense components, AS9100 is non-negotiable, and ask for evidence of compliance with relevant MIL-STD-883 test methods.
  • Beware of suppliers who oversimplify bondline thickness control: A significant red flag is a supplier promising extremely tight bondline thickness without detailed explanations of their process control, tooling, or measurement methods. Consistent sub-25µm bondlines, especially with larger die, require highly specialized equipment, materials, and stringent in-line monitoring.
  • Verify cleanroom environment and ESD controls: For sensitive devices, confirm the supplier operates in an appropriate ISO Class 7 (Class 10,000) or better cleanroom and has robust electrostatic discharge (ESD) protection protocols in place, from personnel grounding to ionized air blowers and verifiable surface resistivity checks.

Frequently Asked Questions

What's the difference between eutectic bonding and epoxy die attach, and when should I choose one over the other?

Eutectic bonding uses a metal alloy (like AuSn) to form a strong metallic bond with excellent thermal and electrical conductivity, ideal for high-reliability, high-power, or hermetically sealed applications where voiding must be minimized. Epoxy die attach uses a polymer adhesive, offering lower cost and process temperatures, suitable for general purpose, non-hermetic, or less thermally demanding applications. Choose eutectic for critical thermal management, extreme environments, or stringent military/medical standards; opt for epoxy when cost, flexibility, and lower processing temperatures are primary drivers.

How do suppliers ensure consistent bondline thickness and low voiding for challenging die sizes?

Consistent bondline thickness (BLT) and low voiding are achieved through a combination of precise equipment (e.g., pick-and-place machines with force control), optimized material dispensing (for epoxy) or preforms (for eutectic), tightly controlled reflow profiles, and robust in-line or post-process inspection. Suppliers use techniques like automated optical inspection (AOI), X-ray for void detection, and Scanning Acoustic Microscopy (SAM) for delamination to monitor and control these critical parameters, especially challenging with large or multiple die on a substrate.

What specific data and documentation should I expect from a die bonding supplier to ensure quality?

A reputable die bonding supplier should provide comprehensive process control data, including statistical process control (SPC) charts for critical parameters like bondline thickness, die placement accuracy, and voiding percentages. You should also expect material Certificates of Conformance (CoCs) for adhesives, preforms, and substrates, along with detailed traceability records, First Article Inspection (FAI) reports, and results from destructive physical analysis (DPA) tests like die shear strength and wire pull testing. For regulated industries, a full Design History File (DHF) may be required.

Is it common for die bonding suppliers to also offer related front-end services like wafer dicing or back-end services like wire bonding and encapsulation?

Yes, many die bonding suppliers offer a range of integrated services to streamline the assembly process. It's common to find companies that provide wafer dicing, which prepares the individual die for bonding, as well as subsequent steps like wire bonding (thermosonic gold ball bonding or aluminum wedge bonding), encapsulation (glob top, dam and fill), and even hermetic sealing. Consolidating these services with one vendor can simplify logistics, reduce handling, and improve overall yield and quality, especially for complex multichip modules.

What are the key considerations for bonding a flip chip versus a traditional wire bondable die?

Flip chip bonding requires precise alignment and controlled reflow of solder bumps or anisotropic conductive film (ACF) directly onto the substrate pads, eliminating the need for wire bonds. Key considerations include the pitch and size of the bumps (fine pitch demands higher placement accuracy), the thermal profile for bump reflow, underfill encapsulation requirements (critical for mechanical stability and reliability), and robust electrical test verification post-bonding. Traditional wire bonding is more forgiving in alignment but requires dedicated space for bond pads and wire loops, introducing different reliability considerations like wire sweep or fatigue.
