Samsung To Use Substrate-Like PCB For Galaxy S9 To Allow For Bigger Battery

by Habeeb Onawole 2

In the last few years, we have witnessed a huge upgrade in a number of components that make up a phone. However, some have largely remained the same, one of which is the battery. Smartphone batteries are still poor in terms of how long they last. The only solution manufacturers have come up with is making them bigger and or adding fast charge.

Samsung’s plan for the 2019 Galaxy S9 is to fit a bigger battery inside it. A bigger battery usually means a thicker or larger phone unless you are able to shrink the size of the other components. Samsung’s approach to the matter is to use a Substrate-like PCB which will let it reduce the size of the main board, making way for a bigger battery.

Substrate-Like PCB

Just like batteries, the main board of phones haven’t seen much change. They still take up a lot of space unlike silicon chips and cameras which are now smaller. Substrate-like PCB or SLP for short, isn’t a new technology, it just isn’t widely used by smartphone manufacturers. Report has it that this year’s iPhone 8 will have SLPs.

The other advantage SLP has over the technology currently in use, which is High Density Interconnect (HDI), is that it allows for thinner connections (<15nm) between components. So since the distance between components are smaller and the board itself occupies less space, manufacturers can fit in bigger batteries.

The Samsung Galaxy S9 will most likely be released in the first quarter of 2018. It will be powered by the Qualcomm’s Snapdragon 845 and Samsung’s own Exynos high-end chip for 2018.

    Lies they won’t fit bigger batteries but more other components and the batteries will get smaller again

    Makes me be grateful that Xiaomi can fit a 4000 or 4100 batteries in their phones without a fuss. when Samsung adds even 100mah it is viewed as a big feat and they’ll try to redesign the phone interior so as to give you slim phones with a glass back that is fingerprint magnet, breaks easily and scratches. Honestly why would anyone who does not use a case prefer glass backed phones
