The Problem This Machine Solves
Eutectic bonding, die attach, and substrate welding all require precise, uniform heating — but many workstations cobble together a hot plate, a separate temperature controller, and a microscope on a cluttered bench. Temperature uniformity suffers, the controller drifts, and the operator spends more time managing equipment than making bonds. The Integrated Heating Stage combines the heating plate and temperature controller into a single compact unit — purpose-built for microelectronics packaging where temperature control directly determines bond quality.
Integrated Design — One Unit, One Workspace
The Integrated Heating Stage combines an aluminum heating plate with an built-in temperature controller in a single housing. No separate controller box, no external thermocouple wiring, no bench space consumed by multiple devices. The oxidized aluminum surface provides improved anti-oxidation and corrosion resistance — critical when working with flux residues and solder alloys that attack bare aluminum.
Key Specifications
| Design | Integrated heating plate + temperature controller — single unit |
| Heating Surface | Aluminum with oxidized finish — anti-oxidation, corrosion resistant |
| Temperature Control | Intelligent closed-loop — high accuracy, continuously adjustable |
| Temperature Range | Ambient to process temperature — continuously adjustable |
| Uniformity | High — closed-loop control eliminates hot spots |
| Control Interface | Direct — built into the heating stage housing |
Applications
- Chip-to-substrate welding — die attach on ceramic, glass, and metal substrates
- Substrate-to-casing welding — hermetic seal bonding for microelectronics packages
- Hybrid circuit packaging — multi-chip module assembly and eutectic bonding
- Optical fiber device assembly — precision bonding of optical components to substrates
- Conductive adhesive bonding — cured conductive epoxies and adhesives
- Eutectic welding — AuSn, PbSn, and other eutectic alloy bonding processes
- Pre-heating — substrate pre-heating before soldering or wire bonding
How It Works
The operator sets the target temperature on the integrated controller. The closed-loop system heats the aluminum plate to the setpoint with high accuracy — the controller continuously monitors plate temperature and adjusts power to maintain uniformity. Components are placed on the heated surface for bonding, reflow, or curing. The oxidized surface resists flux attack and maintains thermal contact over thousands of cycles.
