bridging between 2 pads

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.

0402 bridging

Les, Some of the answers to design or stencil aperture/placement machine depend upon what is the current spacing between your components which you didn't specify. Chip components such as 0402's and 0201's typically have very small reductions in pas

what is ideal or minimun spacing in between 2 pads to avoid bridging? thanks

If you don�t paste / reflow solder on the pads, they will never bridge. ;-) A design with a 0.13mm gap between pads will challenge equipment, materials, and process.

Pad spacing is just one element to consider. Your pad spacing is determined by the pitch (center to center distance between the leads). There are several good resources to find the appropriate pitch per device. Search the archives here or refer to th

Consider using the following hierarchy of rules for pad design: 1. If you have a land pattern in a manufacturer�s data sheet, use it. 2. If the data sheet doesn't have a land pattern, but does have an RLP (registered land pattern) number or JEDEC n

Glen, Although the previous answers probably fit the problem you are having, we recently found that during pin insertion on an Autosplice machine, the gold was flaking from the pins and lodging between the legs of surface mount components. It would

Similar to Coop's comments, above ... Bridging: * Mis-placement: misplaced components, high placement force mushrooms paste * Too much paste: HASL thickness, lead finish, poor underside support, poor underside wipe frequency, printing with too lar

Minimum lead pitch to avoid bridging

Electronics Forum | Thu Jul 05 19:37:15 EDT 2007 | davef

We assume the three leads are lined-up perpendicular to the wave. Without taking corrective action, we know this: * 50 thou pitch will bridge * DIP do not bridge As a corrective action that doesn't invovle a respin of the board, decrease the solderm

Best pratice to reduce bridging on wave

Pallet angle is usually pretty good. Lead length is also another good thing to keep as short as possible. Air Knives don't work that well. Also check your board. Make sure you have solder resist between each and every thru-hole pad. If the board
