'[OT]storage of bulk smt components?'
2008\11\21@160411 by Artie Jones

Hi all,

I have been given a tremendous quantity of surface mount components, left
over from a commercial operation. There are anywhere from 100 to 1000 of
each value, although there are some sandwich sized ziplock bags that are
nearly full!!!!!!! They are all resistors and capacitors, so static is not
an issue. There are 4 boxes of these parts, the vast majority are 0805 and
0603 size. The shipping weight oft he boxes was around 30 pounds each, there
are 3 boxes! And the components are bulk packed, not on reels so there are
literally millions of parts.

They are sealed in ziplock bags of various sizes, but I need some way to
store them in smaller quantities, perhaps 100 or so parts for each value.
The problem is I can't find the value I need easily!!!! I need something a
like a container or plastic box with small compartments, so I can pull some
of each value and put them in the compartments so I can keep it in the
workshop and not have to struggle to find the values I need when I need
them.

Can anyone suggest inexpensive containers that might be suitable for this
purpose??? Storage containers should be inexpensive.

Any ideas??

Thanks,

T

Suggest looking at Akromills manufacturer, some of the dealers are:

www.usplastic.com/catalog/category.asp?catalog_name=USPlastic&category_name=25398&Page=1&gclid=CKq46fqXh5cCFSCysgod0Hq4-A&cookie_test=1
and http://www.graingers.com

The later has huge warehouses located all over the USA and like you
would receive next day.

Artie,

Go to Wal-Mart or your local photo shop and see if you can pick up some
35mm film containers.
Most of these are sort of a dark gray or black color with either a white
or gray top.
I have used these to house many SMT components over the years, and still
have a number of them in my lab.
The last time I got any was earlier this year.  Imy daughter worked at
Wal-Mart for a while late last year
and earlier this year, so I had her ask the people in the photo dept. to
save them for me.  They did.
I have probably gotten about 100 or so over the last 12-14 months.  And
they were free.
Give it a shot.  

If you can';t get any of them, you could always try Wal-Mart for divided
plastic boxes.  They're in the crafts
Section, and usually have 12-20 small compartments.  They're being sold
as a Bead Storage Box, but they work
Well for things other than beads.

I believe Fry's also has boxes of this type.
       
Regards,

       
Jim

Have a look at eBay item 220300124845

Although I don't see just the enclosure itself listed for sale, I
have purchased empty enclosures from them for $19.99 each.

FWIW - their 1% resistor assortments are reasonable value.  The cases
are solid and I haven't managed to empty any of the constents onto
the floor, even though they have been dropped many times.

I am beginning to store tiny parts in plastic envelopes (zip type) that are
then filed in small boxes. The biggest advantage is that you don't have to
store empty space. They are easy to identify with a slip of paper in the
envelope. EBAY is a good source for assorted sizes of Plastic envelopes
cheap.

Akro-Mils makes great products.  My favorite product line from them is their
drawer systems, like this:

http://www.grainger.com/Grainger/items/3AJ39

Another, possibly cheaper, solution is fishing tackle boxes.  Take a look at
your local sporting goods store.  The ones I like for electronics component
storage are $5 each.

I've been using the Raaco A45 and A46 boxes for component storage -- they're
fine for larger SMDs, as long as you push the orange dividers down all the way
(they're a bit stiff and tend not to go all the way down). I've had issues
with 0805 parts slipping under the dividers and getting mixed up though. A bit
of hot glue or Araldite sorts it, but for what they cost they aren't up to much.

The A4 Assorter boxes are much better built, and have separate moulded
compartments (no dividers). Not as versatile, but less risk of SMDs getting
mixed up. They are expensive though (which is why I've only got two of them!)

Maplin have recently started stocking these:
http://www.maplin.co.uk/module.aspx?moduleno=26150

They're relatively cheap, the dividers are movable and lock into the plastic
with a nice 'snap', and there's no gap between the divider and the box itself.
 I've been using them for resistor kits -- one box will divide into twelve
compartments that are just the right size for axial-leaded resistors on paper
strips. Three boxes are enough to cover the E12 range from 10R to 1Meg.

I tend to keep SMDs on the plastic or paper tapes though, with a written label
on the tape to ID them (usually just a Farnell stock number, component value
and size -- e.g. "MF25 680R 123-4567 RoHS" = metal film 1/4W, 680 ohms, P/N
123-4567, RoHS compliant). I tend to use a silver or gold paint marker for
black plastic tapes and a black Stabilo Write4All for the paper tapes. Works
pretty well for the most part, but the silver/gold marker tends to wear off
after a lot of handling. The black marker, not so much.

I have bene using this style of container:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&amp;item=270172299622&amp;ssPageName=ADME:B:EF:US:1123
for some time. They come in several sizes and colours. I have black
ones that are anti-static as well as the colours. Each one is totally
separate so that you can re-arrange them when you need to add another
value in the resistor tray.

I usually keep them in blocks of 50 ( 5 x 10 ) which is really
convenient to put on the bench when I am loading a board. Because
they are separate they can never "bleed" form one compartment to the
other, and each one has a lid which is held by a spring. The larger
sizes are great for things like connectors, switches, push-buttons
etc. The little ones are fine even for things like SOT-23 and SOT-223
transistors and regulators.

Just label the lid with a permanent marker.

John

I got that too, just copy the item number out of the link, and use that as
the search item found it.

I've just found these:
http://www.maplin.co.uk/Module.aspx?ModuleNo=26133&&source=14&doy=26m11

Which are similar, but apparently sold as one solid block, not as
snap-apart-and-clip-together modules.

The ones you linked to are nice, but importing any significant quantity of
them is likely to be somewhat costly. These appear to be a bit cheaper, and
possibly more suitable for e.g. SMD resistors due to the smaller size:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=320317490567

£12.50 for a 50-bin SMD storage box doesn't seem bad to me.

> Just label the lid with a permanent marker.

I already do that. Thank $DEITY for Sharpie markers!

http://stores.ebay.com/toolssales again search SMD storage

They seem to be available ins several varieties from a number of sellers.

Seconded on the cubic configurable boxes from DX, I've gone though 150
at home,  and have ordered 200 more :p

stock up :)
