Vertical bend resistors solder fillet

Electronics Forum | Thu Dec 12 12:54:25 EST 2013 | jaimebc

For selective soldered components, or even hand soldered, with vertical bend components, the body of the component, in this case a resistor, is making contact with the surface of the PCB, making it impossibe to visually see the solder fillet. Or to d

For vertical mounted, axial leaded components; the standoff from the land to the component body should be 0.4mm[0.016in] to 1.5mm[0.059in]. Right?

Hello I hope this helps For a component with axial leaded - vertical The clearance of the component body or weld bead above the land is 1.00mm (0.039in) Component body must be perpendicular to the board The overall height does not exceed maxim

3W. Figure 8-84 shown evidence of heel bend wetting(but no written criteria mention about the solder fillet must present at the heel bend). It is acceptable if the minimum D(3W/75%L)extend from toe which is no evidence of solder fillet at heel bend?

If the solder joint meeting 8.2.5.4, minimum side joint length(D) and also meeting 8.2.5.6, minimum heel fillet height (F) but the heel fillet NOT extend to the mid point of outside bend. It is acceptable?

Davef, Thanks for your reply. Also sorry because I didint notice your ealier reply on http://www.smtnet.com/Forums/Index.cfm?CFApp=1&Message_ID=48991 regarding the normal gull wing lead, the solder fillet must extend to the mid point of outside lead

Your paste should meet the mid-point of outside lead bend. If you cannot meet that, IPC-A-610D, 8.2.5.6 defines the minimum. We agree that it gets confusing when you post multiple threads on the same or very similar topic.

We'd say yes, if it meets both 8.2.5.4 and 8.2.5.6

On one hand, nothing in 8.2.5.4 that states that you need a heel fillet. It only talks to the length of the side fillet. On the other hand, we suggest that you should use 8.2.5.6 to determine if your heel fillet is acceptable, after you have determ

Is there a machine for bending S shaped bends in leads of through-hole components, to keep them off the surface of the board.
