1. Development boards and circuits are quite bulky, how are they miniaturised? Are there specially available "smaller" version components for putting into real world products? How are they mounted on the board? Answer: Boards are miniaturized by using professional PCB design software, selecting the optimum values of components, and fine-tuning their specs. Smaller versions of components are available to size that that you will not be able to solder by hand. So it depends upon your setup "How small you can use". Components can be mounted by hand, semi-automatic pick-n-place machines or on fully automatic machines. Abhishek Bk said:
2. How is the casing for the circuit done? Are there companies that make the casing for you? How are the casings designed? Answer: If you have finalyzed on the schematic; or development is complete on the development board; then you can design the PCB, But before designing the PCB, you need to select the dimensions of the cabinet. Look what is readily available; if not available, then you can get it built from fabricators. It all depends upon what cabinet you want to use. You select the type of cabinet, you select the type of material for the cabinet, and then select the dimensions, Don't go the other way round. Nowadays you can get ready-made cabinets of all shapes, sizes, materials. 90% of the cabinets that you require, are ready-made. There are many companies in India who will supply you these. Open up the magazine "Electronics for You" and will find atleast 5 advertisements for cabinets. Abhishek Bk said:
3. If you are using an adapter as a power supply, and your ics are going to be kept quite close to the pw supply, is there anything risk of induction and interference? How can we protect from that? Answer: Now you have asked a very simple question, with a very huge answer. And this answer will create a lot of posts. I will just suggest you to refer to a thread, where Kai Klass, and Prahlad Purohit had a detailed discussion in the thread "How Good is this Board". I don't have the link right now, but search for it, and all your doubts of interference and noise will be cleared; atleast as a beginner. Abhishek Bk said:
4. And finally, how are the products tested in the real world? There are many ways to do that. You can get testing services from reputed companies. They might as well provide the certificates for the same. ERTL (in Mumbai) is one of them. Please Note: I have not read the other posts in this thread due to shortage of time; Please excuse me if I repeated some points. |
