Product concerned: Sdram memory. Due to the net resistor size and shape (0603, the lead of this component is very close to some vial hole. What is the minimum clearance we must have between a component lead and a pad or via ? For the pcb design th

One thing to consider is the length of the leads protruding from the solder side of the PCB will have an effect. Longer leads will be more prone to bridging than shorter leads with the same spacing.

Hello, I would like to ask you about the minimal distance between components and border of pcb especially V-cut to avoid crack of component during depaneling? I need some standard (IPC or something) where is this defined? Thank you for your support

The courtyard around a 0603 resistor should be: * 0.008" along the short edge of the component / pad * 0.036" along the long edge of the component / pad As you say, the component courtyard should be larger than the spacing between features, becaus

Assuming agressive design rules what is the minimum distance I can get away with between the board edge and a SMT pad and between the board edge and a plated mounting hole ??? (The board is only 1"x2" and the mounting holes are 80 mil dia, 125 mil

We noticed unsufficient soldering on some 0805 chips located between pins from a plastic bloc connector . All chips are soldered with 45� angle. Flux quantity , preheating , contact time and PCB quality was checked. Do you know any international stan

sometime hand solder can cause also. no necessary have to be paste n reflow.:) now i'm facing bridging on 0402 components pads. any suggestions on spacing distance as we're going to re-design the pcb.

The biggest factor is the selective solder machine. Do you want to know the minimum distance that all selective solder machines can handle with no difficulty? If so that will be a fairly large distance. If you are designing for in house boards then y

Dears, I would like to aks you, about minimal distance between solder pads for THT components for selective RoHS soldering. Is there some standarts, where I can find this information? Enclosed is draft, what I mean. Thank you very much for your suppo
