Tips in PCB Assembly

Aug - 24 2015 | By

The final steps in pcb assembly involves the selection of suitable components needed for the finished product. The challenge lies more in selecting the components of the gear, and the least among the concerns of builders is inserting the screws and enabling the connectors.

A builder’s dream is to successfully build the pc without encountering a lot of issues. This can be a simple task but considering the components that need to be handled, the process can be delicate and time-consuming.

A few simple hand tools are all you need to get familiar with the assembly process. The challenge remains in the troubleshooting stage where you need to sort out the problems for the material to work. To minimize the errors in pc assembly, here are some helpful steps that you can follow:

PCB Assembly

Know what critical components are involved when you’re building. Watch out for electrostatic discharge that can largely impact your work. ESD is mostly responsible for hardware damage. As a remedy, you can create your own workspace and use an antistatic mat under the chair. Consider also using a humidifier so you’re sure that you’re working in a dry environment.

You can use protective gear, such as a grounded wrist strap, for extra protection. This also serves as a precaution to eliminate damage applied to the build’s sensitive parts. Using a metal case to your plugged in system is also a good measure.

If possible, avoid dropping the material since this may also lead to broken components. Be extra careful in handling vulnerable parts, especially during installation. Secure delicate components in a safe place to avoid dropping and just let these out when you’re ready to install them.

The critical part of the build happens during installation because components are often hard to handle especially when they are fragile. At the same time, a modification by manufacturers in the way the interface is made makes the materials slightly difficult to handle. You also need to check for slight damages that affects pcb assembly in terms of contact pressure. A slight alteration already affects how the build will function.

When choosing among the different cleaning procedures, take note of the flux that you’ve been using. If it’s the kind that’s water soluble, you’ll probably have to submerge the board in water. While that seems risky, it’s the only way you be able to take full advantage of the flux’ unique shine. If you’re feeling extra hesitant though, it wouldn’t hurt to actually check whether there is no water sensitive component on the board. If there are water-sensitive parts, then you should have used the no-clean kind of flux.

Do keep in mind that moisture could end up ruining your board. So, hours after you have cleaned the flux, especially if you’ve chosen the aqueous variant, you have to inspect whether there are traces of moisture on your proud creation. If there are, you shouldn’t think twice about using any effective drying technique. Well, effectiveness is largely defined by how much moisture is left on the board. Simply put, if the drying needed is only minimal, using hot air might be enough. For more extensive requirements though, baking might be the only suitable choice.

Applying some techniques when conducting pcb assembly spells a difference on the output that you’ll achieve. It might even save you from having to repeat the entire process – and having to spend more on your pcb assembly project. All in all, following the right techniques is necessary to ensure that all risks are avoided (or at the very least, minimized) when you’re trying to come up with a perfectly built PCB.
