We are making a footprint for the L1C1-RED1000000000 led led Datasheet: The recommended land pattern on page 27 of the datasheet shows the pcb pads being smaller than the actual led?s own pads. (leds own pads shown on page 25) -Presumably this is to stop the led from sliding (...)
Hello, Attached is a 110mm x 46mm x 1.5mm Aluminium led pcb. Would the leds ever be layed out on this board by hand (tweezers), prior to putting through the solder oven, or is it always done by pick and pace machines? (in UK/Europe/USA) If they are layed out by hand then we would put all the leds with cathode facing (...)
hi all... i have a small confusion regarding nm or nanometer in UV led. i just want to ask more nm means more distance of light and more superior. actually i am ordering UV led's for pcb developing. i have checked that 420nm to 430nm = 6 $ (10 pcs) 395nm to 400nm = 6.50 $ (10 pcs) 3.80nm to 3.85nm = 8 $ (10 pcs) 365nm to 370nm = 21 $ (...)

Hi I use Cree led on my pcb 12serial apr.36V . I want to protect it to ESD and high vltage such as voltage surges so can i use TVS for it Y capacitor. How can i solve anybody advice
Diptrace (may not be professional) have this 3d view of the pcb
Animated Simulation are not possible on OrCAD. Use Proteus for simulation and OrCAD or Schematic and pcb design.
and the person who gave me those pictures don't have the schematic of that pcb, is it possible form me to code these led's? The whole board seems quite simple, therefore if you start from scratch, drawing unknown devices as empty boxes, would be easy to us deduce their function as well its specifications.
a glass pane terminating as a connector will be usually connected by a "zebra rubber" strip to pcb pads If I were to use a few ULN's, the LCDs are multiplexed. There are 4 COM pins in the LCD. There is a complexity in the LCD's SEG and COM pins. Even when a segment is not glowing, it has to face a voltage which is in pha

....Or any individual country, for that matter. I say in UK, its 10 billion ? (10 x 1e9) (I am including "every" single SMPS, eg, including ones like local 5W buck converters on a pcb in a product.)
The losses due to light emission should be negligible, and the power consumption of the led can be took solely on the current across its terminals against its drop voltage. Even assuming that the OP is referring to a continuous operation ( not pulsed ), the power density over this sufrace size seems feasible to operate at the standard FR4 pcb i
No, I am about to reach the chapter on the built in eagle scripting language in my book. So I was curious if this is one of the possible things that can be done using the built in script of eagle pcb.
SinkPAD is a thermal management Printed Circuit Board (pcb) technology that makes it possible to conduct heat out of a led and into the atmosphere in a faster and more efficient manner. SinkPAD is an alternative technology to the conventional Aluminum pcb or MCpcb providing superior thermal performance for medium to high (...)

Hi, I am working on led bulb. I have made circuit . I have series connection of 16 3.2V led, and a 1K 1W resistor. But the circuit that is on bread board is working fine but with the same circuit on pcb the resistor is getting very hot. Can anybody tell what can be the problem. Mains supply is 220V. Thanks, Nitin
Recently the washer died and while checking LNK304PN and R1 (22ohm), 4.7u450v was replaced to bring it online. However when switched on, immediately getting PE error after ON symbol with wash cycle led's blink. Pressure sensor (E1) is already validated. The machine was working with a older version of pcb and I need to fix the new version and
Some time ago, I modified a cheap dollar-store flashlight by inserting the front led assembly from a faulty 4W mains led spotlight bulb and making the inverter by using the same small transformer from the blown inverter pcb. It turned out to be a very useful light that is capable of operating on a single AA battery as low as 1V with only (...)
Hi, So we have created a pcb that uses the SIM968 module, and we originally used the EVB to test our control code and it all worked fine, sending texts etc. So we then laid out the system as per the datasheet (design guide). We get an error over AT (not specified) but we have the led flashing - the error code is (is cant remember first bit

Where is the best place to post for a pcb designer to layout a simple pcb for an led IR Illuminator? I have the circuit design but I don't know how to use, and don't have the time right now to figure out how to use, pcb design software. I imagine the design would take less than an hour and I am willing to pay for help. (...)
Hello, I am trying to repair a Philips power board, it has some problems with its led indicator, but it is not the point of this post. When I open the shield, I find a little pcb with some discrete components on it. I guess its usage is to inspect the polarity of socket voltage and indicate the condition of lightening-proof. The picture follo
I would like to place a 1206 led on a board over top of a 0.052 hole so that when the led is illuminated, the light shines through the hole. It seems some led's are better than others at shining out the bottom. Can anyone suggest an appropriate led?
Hello, We are doing a 3 channel, surface mount Buck led driver (3x 165W) , which is 495W total. The room on the pcb for this is just 60mm x 70mm. So as to keep the components cool, we wish to use 4 oz copper?but will this mean that 0603 resistors will not be soldered properly? (there are 0603 resistors and caps near the PWM controller).
It's mainly the pcb surface, insulating air layer, inner and outer enclusure surface that defines the achievable heat dissipation. The only relevant improvement in case of a hermetic enclusure would be direct pcb to enclosure metal contact or ultimately complete potting. The external enclosure still sets a power limit. You should talk about e
Hello, We are going to use the Meanwell HRPG-600-48 PSU (48V, 13A, Offline) to power our four 105W Buck led drivers. (Iout=3A, Vout = 35V, fsw = 200KHz, CCM, non-synchronised) All the four led drivers, when considered together, only have 80uF of input capacitance, due to pcb room constraints. Therefore, as you can imagine, most of (...)
yes 4 layer price is almost double than 2 layer pcb
Hi everyone, today i took apart my autoradio which had green lights in it. I am trying to change it to blue, so i took it apart and i found pcb board, and on it some very miniautre led lights geometrical shape is block, length aproximatly 1mm, width a little less, and height around 0.5mm, they look completly white, with no circle on top
I have searched online and found that there are two UV light box pcb exposure methods 1) By using UV leds . 2) By using UV Tube lights. Guide me on following aspects: 1)Quality wise which is preferred/which will give better results? 2)If I have to make UV light box at home then which is faster and cheaper?

Like the title says, this is my first pcb design. It's been through five or six revisions over the last month, and I've arrived at this. I was hoping that some of the folks on here could give me some constructive feedback on my design. The purpose of this board is as a controller for a 10x10x10 led cube using 595 shift registers. Each (...)
Hello, Does any reader know the thermal resistance of typical conformal coating materials? -the following doesn't give figures. Supposing I have a led pcb with ten leds on it , each dissipating 150mW, and I am using the pcb copper area around the leds to cool the leds ( no additiona
Hello, I wish to replace some failed leds on a pcb which is covered in conformal coating (transparent lacquer). Is it possible for me to de-solder the leds, then wipe off any lacquer that may have melted over the pads, and then re-solder a new led onto the pads, and then spray it over with the waterproof (...)

Hello, We wish to get led lamps made by our pcb assembly place. We realise that they will usually buy full reels of the Cree XP-E leds. Though is it possible for them to buy the leds in say half or quarter full reels?, they may be able to get them cheap and only half-full off ebay, or it may be stock that is (...)
Hello, We have a flashing led light pcb, which is in an enclosure which is outdoors (on top of a truck). The pcb must be coated in waterproof conformal coating, to stop it shorting, and yet we must be able to re-program do we do this?...because the conformal coating, once it covers the program header, it disallows electrical (...)
EDIT: I couldn't find any specs on the SAM8118 IC that is driving your ledS. But IF, and ONLY IF, that IC could safely supply enough current, you could POSSIBLY use only a series resistor and led, for the external circuit for each led, INSTEAD of something like the circuit I posted below. In that case, you could just put a current-limiting (...)
Hi everybody, I am currently designing an NFC reader with a PN532 chip from NXP (which is one of the requirements of my circuit). I plan to draw a rectangular loop inductor on the pcb which would approximately occupy a 3x3 cm square (up to 4x4 cm). There will be other components on this pcb such as an led driver, some (...)
It isn't an IC you could buy in a store, it's a small pcb with an IC mounted on it under the black epoxy. It could be anything, I have a similar one here that flashes four led chains but what you describe as transistors are SCRs. Brian.
