Wave and Reflow Soldering

Maintain Solder Quality with On-Demand, Pure Nitrogen

Keep productions smooth with Atlas Copco Specialty Rental fleets of on-site nitrogen generators.

Supercharge Multiple Operations with Atlas Copco Rental's Air, Nitrogen and Power Fleets

In the high-risk world of electronics and semiconductor manufacturing, it only takes one issue to throw multiple processes off course. When a single equipment failure (be it air compressor, nitrogen supply, or power source) happens, what effects does it have across the entire platform? 

Imagine an oil droplet the size of a pinhead contaminating a batch of state-of-the-art microchips — millions in losses and a damaged reputation. With multiple critical operations running simultaneously, even a minor delay can trigger a chain reaction across the entire workflow. That's where we come in.

 

Atlas Copco Specialty Rental delivers a complete solution: from oil-free and oil-injected air compressors to nitrogen generators and robust power generators — all engineered for fast deployment, reliability, and performance. We are at the forefront of meeting your industrial demands, helping you minimize downtime risk, and ensuring operation continuity. 

 

Applications and Potential Challenges

Wave and Reflow Soldering

Wave and Reflow Soldering

Wave and reflow soldering are fundamental processes to attach components permanently to printed circuit boards (PCBs). This process involves pre-heating the PCB and components, applying flux to remove the oxides and facilitate bonding, exposing the components to molten solder, and controlled cooling to ensure joint integrity. With such an intricate procedure in place, a few challenges can occur like oxidation of solder joints during heating, dross formation in solder bath, and thermal profile inconsistency, which can all affect the quality of the solder and impact end-product performance. 

 

With an on-site nitrogen generator in place, you can control the atmosphere with oxygen levels below 10 ppm, ensuring a consistent process control across production runs. 

 

Thermal Process: Annealing and Heat Treatment

Rapid thermal processing (RTP) is an essential semiconductor manufacturing technique, enabling high-temperature treatment of silicon wafers within seconds. It supports critical steps like component stress relief, dopant activation, and material property modification. However, thermal processes come with inherent risks as high temperature can lead to surface oxidation, while uneven heating can result in inconsistent stress distribution and altered material properties. These causes compromised product quality and yield across production lots.

Emergency Power Supply

Even a momentary power disruption can create a domino effect, resulting in damaged sensitive components mid-production, causing data loss, delaying deliveries, and leading to expensive reworks. In a sector that relies on precision and continuous operation, unplanned downtime isn't just inconvenient — it's downright costly. From cleanrooms to wafer fabrication and testing lines, every process depends on stable, uninterrupted power. Whether brief or prolonged, outages can compromise entire batches and impact customer trust. 

That's why a robust emergency backup power plan is not optional, our rental generators are engineered for rapid deployment and reliability to ensure your critical operations stay online when it matters most. 

 

Cleanroom Air Supply

Cleanrooms in semiconductor manufacturing have to meet strict air quality standards to maintain their ISO 14644-1 classification and keep particle counts within limits. The air supply is key to preventing contamination that can compromise highly sensitive processes like lithography, etching and deposition. Even microscopic airborne particles or molecular contamination can cause defects that affect device performance, yield and reliability. To keep these ultra clean environments up to spec, cleanrooms use constant filtration and precise control of air purity, humidity and pressure. Any variation from these parameters will cause process instability, scrap wafers and big losses.

Chemical Vapor Deposition (CVD)

Chemical Vapor Deposition (CVD) used to deposit thin films on semiconductor wafers requires very tight control of gas purity, flow rates and reaction conditions to get uniform film thickness and material integrity. Even tiny impurities in the process gases can cause defects like poor adhesion, non-uniform deposition or electrical failures in the final device. High temperature environments and reactive gases in CVD also pose safety and operational challenges, requiring equipment that can handle thermal stress while having precise pneumatic control and contamination free purging. 

 

 

Dry Etching

Dry etching is a plasma-based process to create patterns on semiconductor wafers and requires very stable conditions to get repeatable etch profiles. The plasma is very sensitive to the purity and dryness of the air supplied, contaminants can affect ionization, etch rates and overall uniformity. Air quality for plasma stability can pose as a challenge, with plasma processes are very sensitive to impurities. A small amount of air contamination can disrupt ionization and cause inconsistent etch rates, non-uniform patterns and wafers to be defective.

Wafer Processing

Wafer processing has tightly controlled stages where particle control, air purity and equipment stability are key. Compressed air are used not just for pneumatic operations, but also for ISO 14644-1 cleanroom classifications and to prevent molecular contamination. Possible challenges like Oil on Wafers can cause devastating effects and even device failure. Even a tiny bit of oil contamination during wafer processing can cause irreversible defects like short circuits or layer delamination, resulting in yield loss and scrapping of entire wafer batches. 

 

 

Other challenges faced by the electronics and semiconductor manufacutring industry can also include: 

 

  • 24/7 Clean Dry Air (CDA) Quality - CDA is critical to prevent contamination in CVD processes. Any air quality lapse, even for a second, can cause film defects, rework or in worst case, scrap entire wafers. Running these air compressors and filters needed for CDA 24/7 can be expensive. Inefficiencies in air treatment can eat into your margins, especially when scaled up to large cleanrooms.

  • Fluctuating Porduction Volumes Requiring Air on Demand - Production cycles in semiconductor manufacturing can vary significantly, so air supply has to be scaled efficiently. Insufficient air during peak production can cause process instability, while over supply of air during low demand can waste energy and operation costs. Inconsistent air supply or pressure can also cause plasma instability and process inefficiencies and longer cycle times and impact overall output. 

  • Minimizing downtime during equipment maintenance - Equipment maintenance is inevitable, but unplanned downtime during wafer processing and dry etching can really mess up production schedules. Extended downtime can result to production delays, longer lead times, and potential delivery backlogs to clients - impacting business relationships and reputation. 

  • High cost of air quality - Monitoring and treating compressed air to ISO standards can be expensive, especially when managing high purity environments. Poor energy efficiency in air treatment systems can add up to operational costs and affect profitability.
