The fragility of supply chains has never been greater. The last few years have made only too clear how quickly one hiccup – be it a factory shutdown, a port delay, or a component shortage – can spread throughout industries. If your business is dependent on complex electronic products, then the stakes are even higher. One of the best solutions to this reality is electronic manufacturing service (EMS). Delegating production to specialized EMS firms helps companies reduce the burden of manufacturing operations with access to global supplier networks, sophisticated procurement methods, and inherent resiliency. The result? Less downtime, reduced expenses and supply chain flexibility when market demands it.

What Is an Electronic Manufacturing Service and What Does It Do?
An electronic manufacturing service (EMS) is a business that designs, manufactures, tests and distributes electronic components and assemblies for original equipment manufacturers (OEMs). Instead of investing in their own manufacturing system and keeping the manufacturing as in-house, OEMs can outsource ...
... the manufacturing to EMS providers, which manage the manufacturing process from the beginning to the end.

EMS providers generally have the following services to provide:

• Printed circuit board assembly (PCBA)
• Sourcing and procurement of parts.
• Testing and quality assurance of the product.
• Logistics and distribution
• Information on design for manufacturability (DFM) consulting.

This model is so common that you can see it in the global EMS market. Partnerships with EMS are vital to a company's competitiveness and agility, regardless of industry, say from medical devices to consumer electronics to industrial equipment.

What are the major challenges in electronic manufacturing supply chains?
Knowing about the problems helps to explore the solutions. Electronic supply chains are a very special chain. They include hundreds of components, several tiers of suppliers, lengthy lead times and geopolitical risks.

Insufficient supply of components and long lead times

This became an acute problem when the semiconductor industry shortage commenced in 2020. If the critical parts are in short supply, production stops. Companies that didn't have good supplier relations or buffer stocks were left waiting months for parts that should have arrived weeks ago.

Single-Source Supplier Risk

A number of manufacturers depend on one supplier for the critical components. But when that supplier is disrupted, this leaves procurement very simple. Natural disasters, factory fires, trade restrictions, and geopolitical changes may cause a sudden shortage of supply.
Cost Volatility

The unit cost of materials is variable. Copper, rare earth elements and silicon are all affected globally by market volatility. If a manufacturer has a small margin, any sudden price change can take a huge toll of company profits.

Inventory Management

Managing stock is an ongoing issue. Having excess inventory means that capital is invested in parts that can be rendered obsolete. In times of high demand, keep too little in stock and production will be affected. But both extremes are not possible.

Product Quality from Farm to Fork: Quality Control Across the Supply
Chain

It is challenging to ensure uniformity in quality if the components are sourced from various suppliers from different regions. Recalls, warranty claims and reputation-damaging product failures are all caused by a single component that fails.
The Solution: How Electronic Manufacturing Service Can Overcome These Challenges?

EMS providers aren't merely manufacturers, they are also the ones directly responsible for managing the complexity of their supply chains for their clients. Let's take a look at how they overcome each of the above challenges.

Utilizing the Global Supplier Networks to overcome shortages
Vetted relationships with hundreds of suppliers in various regions that have been established through relationships with established EMS providers. This wide range of connections allows them to find replacement parts from other suppliers in a timely manner if the primary supplier is not available. They also achieve priority allocation through volume purchasing, a key benefit that most individual OEMs cannot achieve on their own, during periods of high demand.

Investing in a number of suppliers rather than relying on a single source to cut risk.Relying on multiple suppliers instead of one to mitigate single-supplier risk.

Multi-sourcing is an integral part of EMS value. The EMSs choose more than one supplier for each component, and qualify them in advance. When one source is unavailable, another is available and approved. This will significantly cut down the chances of production stoppages.

Strategic Procurement – Cost Control

Thanks to their purchasing power, EMS companies may be able to secure a more advantageous pricing for the components than individual OEMs. In addition, an experienced EMS partner monitors the market and recommends their clients to purchase rates or establish safety stock to prevent rates from rising due to market fluctuations. It helps to level out price fluctuations in the long run with this approach to proactive procurement.

Optimizing Inventory using Data and Demand Planning

Today's EMS companies rely on advanced inventory management systems that dynamically manage inventory and supply chain based on demand. They leverage historical data, customer forecasts, and market signals to assist clients in keeping their inventory levels in check without committing too much funds. Other EMS partners also provide consignment inventory services where parts are kept on-hand and paid for as they are used.

The development and application of the built-in quality assurance across the manufacturing process.

The implementation of quality management is in-depth throughout the whole process of EMS production. EMS providers have high standards throughout the entire process, from receiving components for inspection, in-circuit testing, functional testing, to a final quality audit. Numerous EMS companies are ISO 9001 and IPC certified, giving the client assurances of quality consistency.

In what situation is it appropriate for a company to work with an EMP?
EMS partnerships are more likely to make sense in certain situations. If the following applies to your company, then you should work with an EMS company:
• They do not have the capital or expertise to set up their own production facilities.
• They are also growing fast and require the ability to scale manufacturing capabilities with them.
• They have faced disruptions to their supply chain and require greater supply chain resilience.
• They are interested in concentrating on core business areas such as Research & Development, Sales and product development, but not operations.
• They are in a regulated industry (medical, aerospace, defense) and certified manufacturing and traceability is a requirement
However, firms that have very proprietary processes and production lines or a high volume of production might benefit more from keeping some manufacturing onsite.

Conclusion

Pressure to be maintained on supply chains. The geopolitical climate, climate change impacts, and evolving trade policies are not dying out. It's not a matter of if disruptions will occur in the electronics industry, but whether there are the right partnerships in place to absorb those disruptions.

Electronic manufacturing service providers like Optima Technology are a viable and proven solution. Global sourcing networks, strategic procurement, quality management and inventory planning are some of the tools that EMS partners provide to OEMs for quicker response time, cost reduction and consistent output amidst the ups and downs of the market.
