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 (...)
O.K., pcb exposure box. Shorter wavelength will be more effective for exposure, but only if you have no UV absorbing acryl glass window. Absolute led intensity however matters, too. Need to compare the emitted light power. Fluorescent UV tubes may be still the simpler method.

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
121343Hello friends, We produce single side pcb with CEM-1 laminate for led lights in really competetive price ,details: Laminate: CEM-1, KB 5150 Solder mask: white, Taiyo PSR4000 W3 Surface treatment: OSP or HASL Volume order: >=100sqm Delivery date: 2-3weeks Pr
....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 (...)
How High can you do hand waving descriptions :roll: without a requirement or a comparison is one example of an 6x3 array of XL Cree ledS on ALum-clad pcb powered by one of my surplus wall transformers 20
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
