Hi Danny,
Thanks for the reply. Can you plz comment on the process details carrried
out both in Wave Soldering and Reflow Soldering ?. Secondly, is there any
alignment requirement for the SMD components being soldered by wave or
reflow technique (e.g some fab houses recommend that rectangular
HI Adeel
the following is a brief summary of wave and reflow:
wave: components are placed first, with the SMDs requiring gluing down. the
board is then passed over the solder wave at an appropriate rate.
reflow: components are placed on top of pads which are pasted with solder.
the board is
Hi Adeel,
If you've got a very densed board, you may consider
reflow soldering on both sides. The footprints for
reflow are smaller and you can gain much free space
for the tracks. The disadvantage is that it's more
expensive but you are free to place your components as
you wish. The
Sorry I was not at work due to an operation on my nose!
But thank you all. As I stated, the problem occurs regardless
of type or footprint.
I will call this Remaining Netlisting Macros. Which means, after

My use of the .designator string is because my locator drawing requires all
references visible and where possible within the component outline. The
silkscreen designator should whenever possible be outside the component
outline.

Igor,
I use the .Designator string in my PCB Lib., This insures that it is

design the PCB part I add; assembly out line, .designator, silk screen out
line, keep outs, and placement court yard. As soon as I update the
An Altium support person told me that mouse wheels etc were not supported
(even through SP6) for scrolling in PCB or Schematic.
Good luck,

some people like the assy dwg to look different than the silkscreen
for example someone may prefer on the assy dwg to have all the
designators 'inside' the component outline
this way they are completely unambiguous
on a silkscreen the designators are often 'outside' the outline so that

I use a Microsoft wheel mouse, and with the latest intellimouse drivers it
works fine for me. Others have had troubles that a driver update tended to
fix. Worth a try?

There was a known issue a while back with the Microsoft Intellimouse causing
keyboard shortcuts to stop working, which was fixed by using the Logitech
drivers. The latest Microsoft drivers work fine. If this is a related
problem then maybe a driver update will help your problem?

18 mills by 10 mills.
The same rule applies for all smd resistors and capacitors.

Resently, I came across a Inductor package 1810.
Does any one know what is the actual footprint for this?
Or there is a www that has all the SMD footprint.

There is at least one layout package I know of that will report dangling
lines and their x:y coordinates. Also, I have been told that running the
database through Specctra will remove dangling lines. Though I have never
witnessed the process, it might be worth

how about 180 x 100 mils

my personal thoughts on the spreadsheet method was that it would
only work in the limited case where the track was only connected at one end.
In my past I have found a great deal of stubs where this method wouldn't
work because there were actually two tracks connected at both ends
