Many humans who have been building electronics projects for years are familiar with FR-1. This is because it’s the most now no longer unusualplace substrate. It is to be had in brilliant colorations and sizes collectively with 160x60mm, 320x240mm, 400x200mm, 450x295mm, 610x390mm and greater. Some even are to be had white color. You might also additionally have seen some large Arduino guard manufacturers like Nextpcb & Assembly the use of FR-1 for their projects. But what makes this substrate stand out from exceptional types of substrates is that you can buy it pre-lessen.

FR1 PCB is the most now no longer unusualplace form of copper PCB, and it has brilliant colorations to be had. Whether you’re in reality stepping into electronics or have an prolonged statistics with them, fr 1 pcb might be one in each of your primary substrates. This is because it’s low fee and easy to artwork with. Compared to exceptional substrates, making your microcontroller circuits on FR-1 is easier. This is because of the truth you don’t must worry about desoldering wires first. The great copper lines on fr 1 pcb will maintain your soldered parts, retaining them in area until you’re organized to solder a few different part. If you’re new to electronics, it’s easy in order to solder your components to the FR-1 PCB without plenty effort. If you’re an professional virtual engineer, there’s although severa facts on FR-1 PCB that you can use.

Benefits of Using FR1 PCBs

There are quite a few advantages that consist of the use of FR-1. You can print your virtual projects on FR-1 PCBs to provide them a customized touch. It’s moreover suitable for hobbyists and university college students because it’s cheap and easy to artwork with. One greater advantage is that you can fabricate exceptional virtual components onto the PCBs. We can say this is so because of the truth we don’t must worry about the solder maintaining it down anymore, so we won’t have wires getting withinside the way of our projects. You might be able to shop coins via now now no longer searching for many components. They embody resistors/capacitors, power supplies/motors, etc. You moreover shop time via now now no longer having to make the circuit board.

1. Mechanical Drilling:

You can drill holes as huge as 8 mm in FR-1, and it's going to although maintain the board collectively. However, the substrate will harm if you drill too deep or try to drill a too huge hole. This can be complicated if you want to drill many holes, so you’ll must assume ahead of time. You need to apprehend how many holes you want to make and the manner large they may be, so the board doesn’t harm apart.

X-acto blades are incredible for lowering through FR-1 PCBs because of the truth they’re sharp and with out issues byskip through without breaking them apart. They’re moreover cheap, so there’s no motive now now no longer to use them for this undertaking.

2. Cost Efficiency:

The price of FR-1 PCBs is cheap, especially at the same time as you buy the pre-lessen sizes like 200x75mm and 220x70mm. You can with out issues find out those  sizes on eBay, Amazon, AliExpress at a miles lower price than searching for each one individually. If you’re doing multiple undertaking at a time, then it makes experience to buy pre-lessen ones because of the truth they’re greater price-inexperienced withinside the prolonged run.

3. Reduced Time:

The time it takes to make a undertaking on FR-1 is also reduced in comparison to exceptional substrates. You don’t must solder wires first in advance than growing your circuits. The FR-1 PCBs are pre-lessen, because of this you’ll need to apprehend the dimensions you want, and that’s it. The great problem you'll probably run into is the drilling of holes. We already included this in advance, though.

4. Compactness:

Because the circuits on FR-1 aren’t that complicated, they absorb tons much less space. As a result, you can with out issues match them in a small discipline or enclosure to make your projects greater compact. This is an advantage because of the truth compact projects are suitable for portability and easy storage.

What are the Drawbacks of FR1 PCB?

Some drawbacks consist of the use of FR-1, but they’re now now no longer too bad.

 1. Resin Overlay:

FR-1 PCBs have a thin resin overlay, and they're capable of with out issues get damaged if you do now now no longer contend with your undertaking properly. When cleaning the PCB or disposing of components from the substrate, you need to refrain from the use of a robust solvent. Examples embody acetone/xylene/isopropyl alcohol. The resin on FR-1 is also sensitive to UV light, so you should store your boards in an opaque field after use.

The awesome way to easy an FR-1 PCB is with cleansing cleaning soap and water, then wipe them off with a paper towel. Of course, this is great suitable if you don’t use solvents on the PCB.

2. Solder:

As we mentioned in advance, FR-1 PCBs don’t have soldered components because it’s already pre-soldered. In addition, they don’t have soldered components on their board. This is because of the truth they is probably hard to solder withinside the primary area given that they’re already pre-sensored. So if you want to characteristic components collectively with LEDs, resistors, etc., you’ll need to do your soldering way. There’s greater facts on upgrading your substrate, but we won’t get into that for this undertaking.

3. How to Take Off Components:

Removing components on FR-1 is also a problem if you don’t apprehend-how. You’ll need to use low-temperature solder, preferably 63% tin/37% lead. However, you don’t want to use too immoderate a temperature at the same time as running with this substrate because it will damage the resin. So you’ll need some way of retaining the temperature low, because of this the use of a heat air gun for the way in choice to a soldering iron.

4. Fusing:

If your substrate gets too heat, it is able to fuse, making taking components off an hassle again. This is also related to overheating, so strive now now no longer to overheat your board at the same time as running with them.
