Improving Productivity with Automated Component Delivery

Automation is growing in nearly every sector. Self-driving cars, touchless soft-drink dispensing machines that deliver over 100 different drinks, and robots doing everything from food sorting to helping pack packages. How can the electronics assembly industry benefit from Automation when nearly the entire SMT line is already made of automated machines?

The biggest automation holdout in a typical SMT factory is the warehousing and delivery of materials. Every factory has some kind of warehouse and nearly all of them are manually staffed by workers. As the effects of Covid wear on and fewer people are willing to take lower paid, repetitive work, the demand for automating warehouses and material delivery is growing rapidly.

In the past ten years, there has been a growing focus on automating warehousing in electronic manufacturing through automatic storage towers as a replacement for “dumb” shelving. Not only do the towers reduce labor and required floor space, they also improve inventory accuracy, control and efficiency. The next logical step is to take the materials from the storage to the production line automatically. Autonomous mobile robots (AMRs) are the key to this process. Through integrated communications, the pick and place machines inform the storage towers of a shortage or a new work order, the tower delivers the needed components to the AMR and the AMR delivers them to the line. All without any human intervention.

This paper will focus on the benefits of using flexible automated component handling in conjunction with AMRs to reduce the manpower required for warehousing and delivery and increase efficiency, improve traceability and reduce errors by delivering components to the line just in time.

Empowering Digital Supply Chain Transformation by Utilizing Industry 4.0, Smart Factories, Standards, Smart Contracts and Blockchains

Member Download (pdf)

Companies that place products onto the marketplace, whether they are internally manufactured or sourced from a supply chain, are often faced with ever increasing demands for data from a diverse set of stakeholders, requiring a multitude of different data reporting needs to be identified and requested from suppliers, ranging from: the identification of raw materials; number of products in WIP state within facilities; finished stock levels in storage; demand needs from customers; numerous what-if scenarios; exposure analysis; safe use and disposal instructions; through to obligatory reporting data under chemical regulation to identify the presence of any hazardous chemicals on finished products; through to the emerging Environmental, Social, and Governance data reporting needs in order to gain access to future sources of funding.

Blockchains are often mistakenly viewed as being solely related to recording transactional data related to some form of electronic payment mechanism. Smart contracts enable contracts between buyers and suppliers to create contract terms in an electronic manner and processed in an efficient and automated manner.

This paper contributes to existing literature by identifying a research gap in transforming the currently diverse manually intensive data collection tasks, via digital technologies such as supply chain collection of reporting tasks embedded into smart contracts, with digital data flows supporting IPC-CFX and IPC technical standards, recording data collection requests and responses in real-time within a blockchain, which is then verified by applicable supply chain actors, to ensure data consistency, accuracy and verification.
The proposed design enables companies to address existing state supply chain data collection tasks using as structured framework, enabling appropriate risks to be identified and managed accordingly in a more timely and consistent manner. The design may then be expanded in a consistent manner as new supply chain reporting needs arise.

Strategic Sourcing within an Evolving Aerospace & Defense Industry

Member Download (pdf)

Traditionally sourcing strategies are resolved by a “make or buy” process where companies evaluate if it is more cost effective to make or buy a product. This presentation will explain the six alternative solutions to a sourcing decision; make, partner, contract, outsource, license or acquire/invest (Solomon 2017). Each of these alternatives will have specific benefits or risks that a given team must assess.

An effective committee is essential in determining a sourcing decision. The development of a cross functional committee including various roles from engineering, supply chain, manufacturing, quality and business development will enable a forward-looking strategic approach. This committee will make decisions based on company investment strategies and help to inform how technologies address capability and capacity of both internal and external manufacturing sites.

The ultimate objective of an effective sourcing decision is to balance a company’s internal research & development funds and those of its partners to maximize its return on investment (ROI). When companies provide transparency to their partners, it enables a faster time to market solution at the preferred price.

Evaluation of Compatibility of EnvironMentally Friendly PCB Manufacturing Processes: Additive Inkjet Coating & Surface Finishes

Member Download (pdf)

The challenge of decrease PCB manufacturing environmental impact is here to stay. The rate at which a company can process change is key to strategical advantage. Any increase of the change rate requires resources in R&D. Equipment and material supplier contribute to the challenge by introducing novelties. Two commercially available technologies are additive inkjet coating and sustainable surface finishes (plating chemistry). These two technologies have already demonstrated independently their compatibility with established traditional PCB technologies and their ability to deliver economical saving, less environmental impact and solve existing common issues (residual ink in vias or black pads) [1,2,3,4]. A PCB manufacturing which integrated both technology as a single change would benefit from a strategically high change rate. An Inkjet tool coats one material on a set of printed boards with test patterns (Copper on FR4) with a test design. The same solder mask material, thanks to different printing strategy, presents itself in two cosmetic finishing (matte and gloss). Four sustainable plating chemistry finish the boards with a post-treatment. The reliability test performed on the boards for visual and mechanical test are satisfactory according to screening test devised to highlight early failure modes. The PCB manufacturing environment benefits from this confirmation as a proof of increased change rate.

Thermally Conductive Polymeric Material (TCPM)

Member Download (pdf)

The electronics industry is seeing more data being computed through printed circuit boards (PCBs). For example, to support 5G communications, most electronics will need to increase their processing speed compared to the previous system (4G) in order to support data transfer rates. In addition to the communication transfer rates, PCBs are becoming smaller and contain higher layer counts and power requirements. As a result, newer PCBs (such those used in communication devices, MicroLEDs, and Electronic Vehicles), generate more energy and create more heat. Traditional methods for dissipating the heat (such as metal heat sinks, cooling fans, and copper pipes) are becoming less functional since they add weight to devices and can take up valuable real estate. As a result, PCB designs need a practical way of dissipating heat without increasing the device weight and / or size.

PCB designs need unique ways to improve the heat transfer efficiency while maintaining the flexibility to continue miniaturization and enhance data transfer. One solution to this problem is to use a thermally conductive polymeric coating. This coating could be applied in areas where heat dissipation is needed. In theory, this coating could be used under or near components (IC packaging) on the PCB, under or near MicroLEDs, and / or in vias in order to remove heat. For use in these applications, the thermal conductivity of the coating would have to be greater than 6 W/mK and use traditional methods for application. The coating would not add weight to the PCB or take up valuable real estate since it would be applied as a thinfilm and / or be filled in vias which are already part of the PCB design.
