Let's learn about space parts! "Plastic packaged products" edition
Until now, we have been studying the harshness of the space environment and events unique to the space environment at the component level (TID / SEE).
Last time, we took a deep dive into ceramic packaging products.
This time, we will introduce plastic packaging products that are attracting attention in connection with the word NewSpace.
Plastic packaging in space environment?
Traditional space applications have used Qualified Manufacturers List (QML) Class V ceramics to ensure reliability.
However, low earth orbit (LEO) mission commercial business has increased in recent years.
Applications like NewSpace (such as constellations) require a large number of parts to create satellites in large quantities.
For such a large-scale business, using traditional space components would be prohibitively expensive.
Therefore, plastic packaging products are attracting attention as an alternative to conventional space components.
So, why are plastic packaging products attracting attention?
What is the background behind the attention being paid to plastic packaging products?
- Reason #1: The price is 〇〇! ?
The first noticeable difference is the price.
The price difference between ceramic packaged products and plastic packaged products varies depending on the product, but it ranges from several times to several tens of times.
Businesses that use large numbers of parts, such as constellations, which have been increasing in recent years, cannot afford traditional space parts.
On the other hand, it is difficult to maintain reliability when using consumer products, which created a major barrier in device selection.
However, plastic packaged products can maintain the same reliability as ceramic packaged products while keeping costs down.
It is attracting attention because it can contribute to total cost.
-Reason for attention #2: Because the size is 〇〇! ?
One of the appeals of plastic packaged products is not only their price, but also the fact that unlike ceramic packaged products, the size of the IC is smaller, allowing them to "reduce weight."
As a result, the ability to reduce the final launch cost is also considered to be one of the factors attracting attention.
Recently, we have been seeing more and more in the news, but plans and initiatives by private companies that have entered the space business are called "NewSpace."
These companies often aim to realize short-term, low-budget projects in low earth orbit (LEO), and are actively considering plastic packaging products.
▶Be aware of the risks of using plastic packaging products
After all, what is the use of plastic packaging products for space? ?
As mentioned above, the plastic packaging products for space that we introduced this time are considered suitable for projects in low earth orbit (LEO).
Parts selection must take into consideration the customer's budget, required specifications, required quality, operating period, application characteristics, etc.
At Macnica, we utilize the know-how in the space business that we have cultivated over many years to propose and provide optimal parts to our customers, along with QE/FAE specializing in space.
