How to Make Practical PCB

How to Make Practical PCB. Some time ago there was a fellow who asked about how to make a practical PCB. Questions may be started when colleagues are seeing the PCB size of approximately 15-cm x 22-cm to 80/40-m SSB Transceiver, a fairly complex circuit that I made at that time. From that question, so I write this article. Hopefully can be useful also for others, especially visitors of this blog.

According to my knowledge there are some practical ways to make the PCB is:

   1. Fotoresist techniques, this process takes several tools and materials are: UV light, Positive solution and NaOH-20
   2. Screen printing technique, this process takes the same ingredients as in ordinary printing techniques such as mesh-screen, thinner stencil, paint and others. Tekniknyapun almost the same as ordinary screen printing
   3. Print Directly to the PCB, in this process used a special technique to copy the layout to the PCB that is used in special printing which has been modified
   4. Technique Transfer Paper, this technique is Practical Ways to Make the PCB which I think most cheap and easy

Of the four How to Make a PCB, we can choose according to need, which is more practical and economical. I think personally, to make the same PCB in large quantities is more beneficial if used Screen printing technique because it is cheap and fast. As for making PCBs in small quantities I tend to use techniques such as transfer paper that I normally apply.

But perhaps there is a fundamental difference that I use in these techniques. In this technique typically used a special paper to copy the images to the PCB layout, but here the way I make a PCB using HVS paper used for photo-copies. Here's how:

    * Prepare the PCB track picture that you have planned. To enable it to use the Software PCB Designer
    PCB layout * Print on photo paper with regular ink printer in order to fill the more solid path
    * Photo-copy printouts were at HVS 70-gram paper. Keep the good results of Photo-Copy (solid ink). My place like that per-share Rp125, - with a Xerox machine
    * Prepare the PCB plain, clean the copper layer with a thinner A while rubbed with Foam Carpet normally used for washing dishes and dry
    * Prepare the electric iron, set at medium temperature
    * How then to make the PCB, attach the picture Foto-Copy the path on the PCB with the image attached to the copper layer
    * Make the process of iron with a uniform while pressing, do about 10 minutes
    * The trick then let stand until cool PCBs and soak it in water about 30 minutes. This process is the longest in making PCBs because we must ensure that the paper is completely destroyed / soft and easy to peel
    * Peel the paper carefully and dry PCB
    * PCB is ready to be dissolved
