SMT Soldering & Circuit Board Equipment

What is an SMD or BGA rework station?

In electronic assembly, specifically printed circuit board (PCB) assembly and repair, a rework station is equipment that allows for soldering and de-soldering of electronic components. This is done by applying precisely controlled and targeted heating at the component and the PCB until solder joints melt, flow to form a connection, and cool to solidify forming a strong interconnect. SMD (surface mount device) or BGA (ball grid array) refers to the specific type and package layout of electronic component. Flip chip bonders improve standard BGA/SMD rework with superior heating interfaces. Most common electronic components that are repaired or reworked today are SMD type and are mounted on the surface of the circuit board, hence their name, surface mount device. A BGA is a subset of surface mount devices, with connections in the form of solder balls arranged in a grid array under the package die. In order to safely repair or replace such components, a rework station must have more advanced features than a traditional SMD rework station. This includes machine vision like split vision optics, precision device placement and removal capability, and computer controlled thermal cycling. This is why in the industry a “BGA rework station” is a term used to describe a more advanced rework station capable of handling general SMD components but also specifically BGAs.

What is a reflow oven?

The process of soldering electronic components specifically, surface mount devices, onto circuit boards during PCB assembly involves heating the circuit board until solder paste melts and creates a solder joint. This is performed in a machine called a reflow oven or reflow soldering oven. There are various types like small benchtop, standalone, batch, and inline conveyor systems. The reflow SMT ovens utilize nitrogen reflow for enhanced reliability of the soldering. Heating technologies also vary and include air or nitrogen convection, infra-red, vapor phase, and conduction. For volume production environments, a large inline convection oven (15ft – 20ft long) is preferred as it allows to streamline the SMT assembly process and has high throughput. The reflow simulator provides advanced thermal monitoring with minimal input due to the programable rework cycles creating reliable quality control. For small volume applications, a batch reflow oven is best if it does not sacrifice performance and profiling capability. This is especially the case when a facility has limited floor space. There is no one fit solution for every product and some types are better suited for specific applications and throughput requirements.

Our soldering equipment and SMD rework stations allow for ultra-precise component placement within 5 microns, utilizing the best in advanced mechanics and software technology. All of our PCB machines and surface mount soldering equipment products are seamlessly integrated within our user-friendly online software. Our state-of-the-art PCB machines, like the flip chip bonder, improve standard BGA/SMD rework with superior heating interfaces that carefully target solder joints for precision placement and reliable connections. Our software monitored air and nitrogen soldering products are paired with crystal clear imaging/component alignment, allowing for accurate soldering applications without disturbance of adjacent SMD components. For high-value, reliability soldering, our PCB machines and reflow SMT ovens utilize nitrogen reflow for enhanced soldering reliability. Numerous industry studies have shown that nitrogen gas effectively prevents oxidation at the solder joints, even when flux has burned off. This allows for improved connectivity and stronger joints between the components and the surface media, preventing unnecessary rework or circuit failures. With our reflow simulator, reliable quality control is easily accomplished with advanced thermal monitoring and minimal operator input due to programmable rework cycles. Our system provides detailed system test logs, and reliable resistance data automatically synced online for pin-point results. With interchangeable carriers available, our soldering equipment is compatible with other IPC or custom-designed test coupons.
