Is it another circuit that is repaired with a universal board? Is it because the universal board can't get the circuit and layout that you want? For today's electronics enthusiasts, the universal board can't meet the production needs, but find the manufacturer. It's not a good deal to make a PCB model, a few dollars a board... Is there no way? And slow, at this time, the photosensitive plate is born! Low cost, easy to manufacture, can easily build complex circuits or even stickers Chip circuit with high precision. Convenient and practical, it is the advantage of the photosensitive circuit board! Today, I will use the simplest 20 "straw hat" LED parallel circuit to demonstrate how to give full play to the advantages of the photosensitive plate - my circuit is neat, convenient and easy to use! 1 Materials and tools ○ Photosensitive circuit board x1 block ○ Ferric chloride x1 bottle, or environmentally friendly etchant x1 package ○ Photosensitive plate developer x1 package ○ Transparent plastic x1 roll ○ pencil x1 ◠Table lamp x1 ◠Glass piece (the thicker the better) x1 ◠Plastic basin or crisper x1 (note that it must be plastic!!) ◠Utility knife x1 ◠Steel ruler x1 ◠Electronic scale or balance x1 (unless you want to use up all the medicines at once) ◠Stopwatch, watch, clock, can time ◠Flat head dice x1 ◠Electric drill, bench drill, can punch holes. Be careful to use a fine drill bit! Approx. 0.8mm. 2 Draw and print your circuit diagram! First of all, of course, draw the circuit diagram. Here I use a PCB design software called Sprint Layout. As for the use of Shenma software, I can't control it... However, I still recommend Sprint Layout to the rookie friends! It has won countless rookies because of its simple operation and easy to use! Draw a circuit diagram. By the way, this Sprint Layout needs to be printed... I have a printer at home when I have nothing to say, no printer to go to Baidu to check "Smart Rrinter virtual printer crack version", this is a very practical green software (of course After you want to crack it, you can put any document -- as long as there is a print option, convert it into a picture with multiple N formats, and then take the picture to the print shop to print, which saves you from holding one. The LAY file is going to print, and people can’t open it... Ok, now you have printed the circuit diagram! (You can use ordinary A4 paper, the lighter the better) Cut it according to the size of your design! Be careful! It should be noted that please carefully observe the printed lines, sometimes there will be disconnection or short circuit... Yes, any defects, the photosensitive plate will follow you. So if it's an inkjet printer, please loosen the line spacing a bit. If it is broken, make up the line. If it is shorted, adjust the line spacing and reprint it! If you have a laser printer, please ignore this paragraph... 3 Start to get sensitive! In the middle is the old version of the gold plate (TwT has expired), the left is the new version of the plate. On the far right is a ferric chloride block, one bottle. Below is the photographic plate developer. Many people ask about the price of the photographic plate. In Guangzhou, where I live, Gangding New SEG Electronics City, there is a third floor, 10 yuan can buy 100 & TImes; 150mm huge board, it is enough. The bottled ferric chloride is more than ten yuan, which can corrode N multi-circuit boards. Imaging agent, 1 yuan thing... Cut the circuit diagram. Note: Due to the sensitivity of the photographic plate to light, I turned off the lamp and there is a way... 144 Port Fiber Patch Panel is not only does it provide physical security for sensitive network connections, it also promotes better organization.144 Fiber Patch Panel can suit for FC Adapter , ST Adapter , SC Adapter , LC Adapter etc,Suitable for ribbon and bunchy fiber cable.144 port fiber optic patch panel Components have Cover, inner components, fiber connecting protector Inner components.And inner components have Bracket,Fiber Optic Splice Tray,Fixing Device .The 144 Fiber Patch Panel Environmental temperature is -25 - 55°C. 144 Port Fiber Patch Panel 144 Port Fiber Patch Panel,144 Fiber Patch Panel,Fiber Optic Patch Panel 144 Port Foclink Co., Ltd , http://www.scfiberpigtail.com
