hi i am using orcad software(capture for schmatic & Layout Plus9.1 for PCB designing). i need footprint for smd type resistors, capacitors, crystal, LED, 6 to 12 pin IC, max232 & 2 to 16 pin connectors. anyone say where to find foot print for these components in layoutplus library.
Can I use the 0603 packet smd capacitors at 60v. (Capacitors values are 100nF and 10nF.) Also dou you know max. operating voltages of other packets?

you need ipc-2222 standart which is include smd and thr footprint size if you are look at tis forum you find it and look at the following adress /* www.toplinedummy.com*/
I want to make an 1.5pF Capacitor in series with a 4nH Inductor and then the C+L in parallel with a Resistor. I am wondering how to make the pad design for this three smd compnent? Thanks in advance.
Hi, Im new to PCB design in general, more specifically to PCB editor 16.2. I am creating a passive structure with my own package footprints. My problem is that i do not know how to connect two pins of different packages without getting the DRC spacing errors. My pads have smd openings on them. Am I not supposed to use the add connect command(F
do you know any smd push buttom for altium designer?
Hi Folks, I have a doubt about footprint design. Is there any difference design for a smd pad in wave solder process and reflow solder process? I hope someone can help me with this question! Best regards! :smile:
I have bought several OPTEK OPIA412ATU optocouplers, from the OPIA400 range. The datasheet doesn't give much in the way of soldering footprints, just that this type is "Package Style A", which may be an internal OPTEK name. The dimensions are given
I am trying to figure out how to avoid tracks getting routed in between the pins of resistors etc of surface mount components. I could make up rules for each component on the PCB but that would make a big mess. So I am looking for a global kind of rule that would cover say groups of particular types of components. Anyone who can point me in the rig
Hi, I have a question regarding dimension tolerances, which are given by manufacturers. For example this ceramic capacitor: . The one I choose is 0603 in imperial. The tolerances for the Length and Width are +/- 0.1mm. The lead width is 0.35mm +/- 0.25mm. it's about 70% tolerance. Since I'
Hello, I'm currently working on my first full-smd PCB. In the past I used some electrolytic capacitors like a 47?F/6V, 471?F/16V, through hole version for my PCB's. Now I'm looking for smd versions. I need to know the size of the footprints. Are they standardized like the through hole versions. I'm looking for electrolytic c
Yes, sure there is some libraries included in orcad, and of course I realize that I have to do a lot of footprints myself (and I do...) But does it realy make sense that everyone is doing the same job over and over again to create very common footprints like SOT223-5 SOT23-5,6 smd electrolyts modern TSSOP and so on. Doesn't anyone know (...)
MOV stands for METAL OXIDE VARISTOR...a protection device used on teh PCBs. There are disc type, radial type and smd varistors available. Check for varistors, then you should be able to find different types of packages and their correcpsonding footprints.
Well, I found the library on OrCAD that contains many footprints of smd its name is SM ... But i wonder, how can i know value of surface mount resistor or capacitor from data on them?!?! Is there certain code or something like that for it? Thanks in advance, ahmad,
Hi I am doing projects and products mainly using MCU . Presently I am using Orcad for My PCB purposes. I am doing circuits normally with say fits in range of 15Cm*10cm. ~! The components are DIP or smd .Never BGA or any such complicated footprints. So far I have not done any circuit simulation . I wish to learn a simulation tool
Hi Folks, We recently migrated to Allegro ver 16 from Pads layout 2005 spac2,we could able to convert the Pads pcb design file to Allegro,the pcb file is 4 layer,later we extracted all the footprints in separate folder and set the path in the user preferences. Now while i try to compile the schematic alone in which i had entered the footprints
1) you need to connect using off page connectors to connect the nets. 2) you need to go through the IPC7351 smd footprint standards to understand the different footprints.
Hi Keith, You are fully correct! I makes i.e. my footprints over long time so, that the pads are pro side minimum a half mm overhangig, longer_I have had never problems by (hand)soldering. In all cases so small smd will be soldered with modern and feinst soldering tips. But we know it. :-) Best greetings! K.
Hi All, I designing some footprints (quite a few actually) in Altium for a PCB that I'm currently designing. A quick and simple question: If i'm given dimensions in terms of tolerance (i.e. an upper and lower limit) (but no mean value), what dimension should I take for my pad size, chip dimensions etc? The particular chip that i'm currentl
im using altium designer 10 for creating my PCB. now i want to create a smd board but my altium library doesn't have 805 component library.where can i download it?
how about 1/2 pitch smd type: Unfortunately not available as 3 position switch....
Hi, I want a suitable footprint for smd electrolytic capacitor 470uF/25V and 1000uF for Altium, but can't find any thing. please help me to find it. Thanks.
