1. No Professional PCB Etching Equipment
Without a doubt, undertaking a DIY etching process can be fun and exciting. There’s nothing more satisfying than having a creation of your own that goes ahead to function as you desired. But before you go ahead and etch your PCB at home, you must have the necessary equipment.
Do you have the right materials to undertake the etching process on your own? Some of the professional equipment that you need in this case includes the following:
·Steel wool or Sandpaper
Unfortunately, a majority of DIY PCB enthusiasts lack the professional equipment necessary for carrying out PCB etching on their own. For example, if you don’t have rubber gloves, your hand may end up getting strained. Therefore, having the right equipment is essential to etch a PCB that will function as desired.
2.PCB Etching Reagent Time and Temperature Control
In PCB, etching is the process where you use a reagent or strong acid to effectively cut into unprotected sections of a surface to come up with the intended design. In modern production, there is a need for several chemicals when creating the proposed layout.
Copper etching a PCB requires reagents such as Ferric Chloride and Ammonium. But to ensure efficient print of copper, the reagent must be maintained at specific temperatures. For instance, ammonium persulphate tends to decompose when heated.
If you want to ensure that the etching process runs smoothly, you must control the etching reagent at specific temperatures. Unfortunately, such is challenging when etching PCB at home as enthusiasts may lack the time control needed to measure the etchreagent’s temperature get.
3. It is easy to lose the gloss of the PCB surface
The most significant difference between a gloss finish on a PCB and a matte finish is more aesthetically. A majority of individuals feel and think that gloss finishes look better. They are shiny, reflect light, and look lighter. A gloss finish on a PCB is also scratch-resistant.
Again, while it is fun and exciting to produce printed circuit boards on your own, you must remember that you can quickly lose the gloss of the printed circuit board surface. By hiring a professional, you’ll be in a better position of being provided with a PCB containing a high-quality gloss finish.
Professional PCB makers understand how to develop glossy PCB surfaces that come with plenty of benefits such as the ones mentioned above. However, by etching PCB at home, you’ll lose the gloss of your PCB’s coatings.
4. Etching PCB and PCB Related Functions
Etching printed circuit boards are highly related to the function or the role of the PCB. Engraving gets rid of excess copper to reveal the predetermined desired circuit pattern. There are several printed circuit board etching processes that PCB designers use.
Some of the most common printed circuit board etching methods include chemical etching, laser PCB etching, and plasma etching for printed circuit board manufacturing. You choose all of these depending on the function of the PCB.
Unfortunately, though, plenty of PCB enthusiasts don’t understand that etching a PCB is related to the purpose of the PCB. To ensure the quality of your PCB, you may have to seek the services of etching experts since DIY at home is difficult to guarantee.
5. PCB Etching Complex Process
A majority of printed circuit board enthusiasts and manufacturers don’t understand how to etch copper on PCB. Etching printed circuit boards is not an easy process, as you may imagine. It is a highly complicated process that, when done wrong, may lead to the production of ineffective printed circuit boards. Doing it on your own is risky, and therefore, highly discouraged.
Since etching printed circuit boards is a complex process, you may need to seek a professional’s services for assistance. Do you have the necessary tools and chemical reagents essential for etching your printed circuit boards? If not, then you’ll be unable to complete some complicated steps associated with printed circuit board etching.
6.Thickness to control
Do you know the standard width necessary for a printed circuit board? A majority of printed circuit board designers believe that the standard thickness should be 1.57 mm. To a certain extent, this is somewhat true. Even though there’s some truth here, such are the dimensions used earlier in PCB fabrication. Therefore, we can regard 1.57 mm as the actual thickness of the PCB.
Today, though, many changes are taking place with a lot of people and industries demanding thinner electronics. With this, there’s a surge in demand for smaller PCB, such as 0.2 mm, 0.4 mm, and 0.5 mm boards. So, how do you specify the thickness of your PCB when making it by yourself? How do you effectively control the width of your PCB?
When finalizing your PCB’s depth, you need to consider factors such as flexibility, weight, cost, and impedance matching, all of which you might not be aware of when undertaking such a project on your own.
