How come this tiny ultra familiar component is running out of stock ? The information raised by constructors and vendors states that the unexpected growth of demand lead to a recurent shortage of products as supply of million of parts per month and who are bound to the availablity of detail suppliers (like I do!). The parcel arrived in my mail box 5 days after the order date, as announced !!! This is great news as we are all eager to get the real asking for adjusted fare rates depending on delivery times DHL told me that they have only one delivery mode: asap ! Here comes the smart part. We all know about the importance of the first seconds in a meeting, the first words and the first attitudes. As expected, the PCBs are wrapped in a vacuum sealed plastic bag. This is state of the art. Here are a couple of pictures taken with my modest means and my very limited skills at taking pictures: What else can I say ? The pictures speak for them selves, delivery times are almost as short as delivery times for European based PCB Once we have our gerber files ready, it is time for “printing” the PCB. For a long time (and a long time ago) I used single sided coated copper Bakelite boards. Then I would copy the circuit  on copper using a special permanent ink pen (in negative) and immerse the board in a iron perchloride bath… Well, I understand that you could laugh at that, however, it was a quite standard manufacturing procedure in the so called “radio clubs” in the 70’s, and I recently heard that a mixing table (deluxe type, featuring 8 channels !) that I made After that came the time of circuits drawn with bitmap editors (once again, I understand that it sounds like prehistory) printed on transparent plastic sheet (at the time of the overhead projectors…) using my good ol’HP 4L laser printer which was perfect for the job. Then I used these printed slides in a custom made UV light box. After a revelation step, the PCB would be immersed in a more ecologic acid
