Indium Bump Interconnect (IBI) Flip Chip Bonding | finetech GmbH
Abstract – The increasing demand for technologies such as infrared (IR) thermal imaging sensors, quantum processors, and micro-LED displays drives the need for advanced interconnect solutions. These technologies require fine-pitch Indium Bump Interconnects (IBI) for high-density flip-chip bonding. Larger chip sizes, sub-micron alignment, and extreme environmental conditions pose significant challenges. This paper highlights solutions addressing these challenges, enabling high-quality bonding for IR thermal sensors and other applications. I. Introduction Indium Bump Interconnect (IBI) is crucial for applications like IR thermal sensors, quantum processors, X-ray detectors, and micro-LED displays. Among these, IR sensors represent a demanding use case, requiring precise bonding of fine-pitch micro Indium bumps to substrates. Challenges include maintaining co-planarity, preventing contamination, and ensuring mechanical and electrical reliability. II. Indium Bump Interconnect Flip Chip Die Bonding Die bonding process Bonding methods range from cold compression to thermal compression and formic acid reflow, depending on application requirements. Achieving high yield during trials and production is critical due to the high cost and complexity of materials. Material preparation and handling Indium bumps are vacuum-deposited and protected with photoresist. Cleaning and kitting processes minimize contamination and handling risks, reducing preparation time and ensuring material integr...

Voltera: Dispensing Solder Paste on Factory Fabricated PCBs
Printed circuit boards (PCBs) are essential for electronic circuits, providing mechanical support and electrical connections for components. Factory fabricated (or sometimes called prefabricated) PCBs are pre-manufactured, ready-to-use boards that simplify assembly and ensure consistent quality in electronic devices. Contact: sales@voltera.io or +1 888-381-3332 ext: 1 Summary of Materials and Tools MATERIALS USED T4 Solder Paste Sn42Bi57.6Ag0.4 SUBSTRATES USED Factory fabricated PCB (FR4) TOOLS AND ACCESSORIES V-One PCB printer Tweezers Clamps Thumb screws Disposable nozzles Project Overview Purpose The purpose of this project was to demonstrate the feasibility of dispensing solder paste on factory fabricated PCBs precisely and reflowing the solder paste automatically. Design The board we selected for this project was a PCB used in the module hub of our NOVA material dispensing system . Since we designed the board in-house, we had the Gerber file for this project, which we uploaded into V-One’s software. Gerber file loaded into the V-One software Desired outcome The solder paste should be evenly dispensed on the designated spots of the FR4 board, with no overflow or voids. Once reflowed, the PCB should fit into the bottom of NOVA’s module hub. When connected to power, this board will allow NOVA to capture images of its work area. Front view of NOVA showing its module hub and work area Functionality The PCB contains a camera, LEDs, and other components that enable NOVA to c...
