There are several processes that we use for your circuit boards while they undergo PCB assembly, and we thought that we can share them with our clients who are consumers of electronic components. These processes also apply to building the PCB prototype because it is important to know the correct process to save money and time and come up with the highest quality product.

PCB AssemblyDuring the stages of drafting, designing, and manufacturing, most of our engineers would create a prototype so they would know what components to use and how to place these components on the circuit board. They also do some tests to determine how much they will need for the final task before starting everything. This is a critical stage that must not be ignored or rushed, and it is also the ideal reason to test a certain process and find out the results.


Basically, creating a prototype involves two process categories, which are:

1. Subtractive

To complete the PCB assembly, any excess copper coated plating will be stripped off in this process. You can choose from the following options:

2. Milling

This process is a common way for us to manufacture PCBs through the use of a milling machine. It creates the brunt of the product. The kind of device used is also called a “PCB Prototyper,” and to create the circuit board, it is commanded by x-, y, and z-axis software.

3. Silk Screen Printing

A PCB can be manufactured through the silk screen printing process just like that used in printing images and text on T-shirts and other articles of clothing. It is a bit different than printing shirts, but this process still uses ink to build a part of the circuit board.

4. Photoengraving

Through this process, the photoresist is taken off. Only the conductive plating is left because the PCB needs it for it to work properly. This process of PCB assembly also uses etching and engraving.

5. Additive

In contrast to subtractive, this process adds the copper instead of stripping off the excess. Like photoengraving, the additive process is a popular process that we use through laminating and subjecting the circuit board to a chemical bath that coats it with the required conductive components. This is the most common way that we use to manufacture a PCB.


Depending on the function of the circuit board and the reason we do the PCB assembly, different PCBs tend to require different kinds of processes for them to work. For this reason, we need to have a shortlist of the processes that we would try first. In a way, this is the “wish list” of your processes.

These processes are required when we manufacture a PCB prototype. However, we only choose one for every circuit board. Some of these can be cost-effective, other processes can reduce the time needed on our total PCB manufacturing project, and there are also other processes that can do both and perhaps even more. Again, so that everything can work within the budget and time, this depends on the PCB, the type of project, and the reason for manufacturing them. As your PCB manufacturing partner, we can assist you in determining the best process for you.

Create the Prototype

After deciding on the design and process, it is then time for us to build the prototype and check how everything will work out. This process is simple: you send us your desired designs and just wait for us to send back the prototype.

During this stage, you could determine if the chosen process would work for you and decide what you would do with the remaining PCBs for the project. You can stay with the process if you like it, or try another one and build a different prototype.

Building the PCB prototype is an essential part of the whole PCB assembly process. We can try this with your batch order so you can notice the difference it will give you in terms of the outcome and quality of the products.

signage software

In a world where information is very important, it is also important to have the medium to send it out with, whether it is a public announcement, or an advertisement. This is when a media signage can come into play. Digital signage is a type of signage wherein one can easily relay information and also change and update the information as one would see fit.

Such a way to relay information is useful in a lot of ways. A media signage for retail purposes will allow one to advertise their product easily from even just outside their store. It will also be at an advantage for them if the means is through a digital signage. A digital signage will allow one to post their new items easily, and if any changes will be needed for their signage, updating the information can easily be done.

Media SignageOther establishments can easily use a media signage. Government establishments can use a digital signage to give public announcement, show real-time news, or just to advertise new attractions. Hospitals can take advantage of a digital signage by giving announcements for incoming and waiting patients, or in some cases, it can provide entertainment to a sometimes boring waiting area. Schools and churches also use this to quickly give information that students and church-goers will find useful during their stay in the said establishments.

Making a media signage is not an easy task. One would need resources to create an effective one. A digital signage can be easy to create, but one would need a reliable system to do it, and that reliable system will be Media Sign Pro for Mac.

Media Sign Pro for Mac is a program that will aid in creating a digital signage no matter where it will be used with. It features an easy-to-use interface so that even one that is new to a computer can use it. Creating a signage is also easy since you can find templates that are already pre-installed in the software, so that you can just use one and edit or customize it to something that will suit your need. It can also accommodate different types of media so that you can make your signage as interactive, or eye-catching as possible.

In creating a digital signage, Media Sign Pro will have “Zones” that will allow you to place a certain type of media in it. Date and Time zones will allow you to place the current time and date in real time. RSS feeds will have its own zone for anyone to be able to see the advertisement in real time. This also goes well with a Twitter zone and a Web Content zone, which can then show Tweets from those who had seen the signage, or show contents from the Internet, which may include video streams and such. A text zone is also available so that one can place more details in the signage, and Image, Slide Show and Video zones are also available to place more content into the signage, maximizing its means of getting attention.

Another advantage of the Media Sign Pro is that it has a lifetime license. There will be no server connection requirements, and no other extra fees to pay in order for you to continue using it.

Media Sign Pro is made for the Mac, ensuring that your digital signage is placed in a reliable system. You can take advantage of the ease of use and flexibility that Media Sign Pro has with the help of a Mac, and updating your signage will be as easy as doing a few clicks. A Mac is known to be stable, and you will not need to worry of any updates that will happen periodically, nor of any virus issues.

Having a media signage is indeed necessary, and having the correct tool is needed. The Media Sign Pro for Mac will be the better choice if you want something that will be well worth your time and money.
