I must admit, that despite not doing it for years, because of reasons I read or discovered from the assembly department. I have started doing it now though, but only where the gap is big enough to drive a double decker
bus through... :-)
I won't go between a resistor or cap of below 1206, electrolytic caps only if I really need to.
AFAIK With electrolytic caps it's because they can leak underneath & erode the hidden track.
But I have never come across that, so I pay it little attention these days, just prefer not to
route between the pads if it can be helped.
I have found that these days, given how much better they are at it the assembly dept does
not have any problems as long as I follow my normal track/pad design rules etc.

Subject: [DC] Routing thru pads question
I am debate with some people in regards to routing through pads
of components (i.e diodes, caps, Resistors) I was always taught
not to do this but I can't remember from whom. Especially with
the smaller and smaller these parts are getting. But I am seeing
this being done today more often at my work by other designers.
I also see necking down to route in between connectors,
and IC's.
Please let me know what others are doing and why.
I am currently training 2 new designers to my company and I want
to make sure I am guiding them in the right direction.
I never got the luxury of being guided at work but have taken many
classes
over the years from people such as Mary Sugden, Gary Ferrari,
Wayne Pulliam and many more. This instructors have instilled in my
a great set of design philosophies that have made me a successful
designer and I want to make sure I do the same with whomever I get
the luxury of training.
Thank you all for your help in advance.
