ASMPT presents optimized Odd Shaped Component (OSC) Package

“OSCs are commonly placed onto the almost fully assembled circuit board at the end of the production line,” says Petra Klein-Gunnewigk, Senior Product Manager Placement Solutions at ASMPT SMT Solutions. “At this stage, a mistake would make the entire circuit board unusable. With modern processors, each of which can cost several thousand dollars, such a mistake can have huge consequences, which is why investing in reliable placement machines is doubly worthwhile.”

New challenges arising from complex ball grid arrays

In addition to classic OSCs for power electronics, such as plug-in connectors, it is mostly ball grid arrays (BGAs) and complex system-in-package modules that pose special challenges for manufacturers. These components may already have several thousand contacts today, and for AI chips, contact numbers in the five-digit range are no longer a rarity. On top of this, they are often asymmetrically structured so that their functional center of gravity is different from their geometric center.

Improved solutions: SIPLACE OSC Package and SIPLACE placement head TWIN

Selecting SIPLACE placement machines from ASMPT gives users a competitive advantage in this demanding market segment. The SIPLACE OSC Package masters the safe placement of OSCs through the precise interaction of placement head, vision system and intelligent control. To name just one example, the machines determine their optimal placement speed based on the mass inertia of the respective component.

A precise 3D coplanarity measurement system checks the component’s planarity. This is crucial, especially with large components, for ensuring that all of the component’s leads make secure contact with the circuit board. Additional pre- and post-placement inspection capabilities that are into the SIPLACE placement machine detect potential errors such as foreign materials at an early stage. This avoids time-consuming repairs or having to scrap the entire board – without having to invest in special equipment. Even PCB warpage is detected and automatically compensated. The machine reliably detects components with bent pins or fine hair cracks and discards them automatically. Each component gets inspected multiple times. And to move the components, many OSC-specific grippers and nozzles are available.

The SIPLACE placement head TWIN in the VHF version (Very High Force) is another important factor where OSCs are concerned. It handles components weighing up to 500 grams and places them with forces of up to 100 newtons. Additionally, it can place components measuring up to 200 × 150 millimeters. A snap-in control system makes sure that connectors engage correctly.

Many years of experience, customized solutions

“Whether you are dealing with OSC heavyweights for power electronics or highly complex BGAs for AI servers — with our decades of experience in all areas of electronics production we find the right assembly solution for every new technology,” says Petra Klein-Gunnewigk. “And if standard parts are not sufficient, we can develop customer-specific solutions on demand, ranging from special grippers to custom-tailored nozzles.”
