Do you have a trick for cutting the pins? I can never get any of my side
cutters in close enough.


**Look for 'flush cutters'. That said, a credible argument can be
mounted to suggest that cutting pins after soldering is not a good idea,
as the stress of cutting may cause a fracture in the joint. Unlikely,
but possible. Best to cut first, then solder.


**Oops. Ignore that. I mis-read your post. A good desoldering iron will
do all you require.

Actually I usually try to cut pins on chips when I'm trying to isolate a
fault and don't want to cut the PCB (or veroboard) tracks. A bit of
component lead is soldered over the break after I'm satisfied. I have
managed it sometimes, but with great difficulty.

I've seen similar devices in use for the last 50 years and have never
known anybody hurt themselves with one.

Probably because the devices they use don't self-disassemble the way
this one does.

I don't buy that much from Jaycar, RS gets most of my business. Jaycar
remain useful for things I really want today, and occasionally when they
will sell the thing I only need one of for a price that's less than I
have to pay RS for the requisite minimum number.

From where I live its 20 minutes to Jaycar, 40 minutes to Altronics,
over an hour to RS, the others aren't in QLD so a day or maybe two.

So its usually Jaycar if they stock what I need.

Dremel :-O

I have small sidecutters that do the job, approx 1/2 size of regular
size cutters. I can't give you a brand name as they aren't marked and I
can't remember where I got them from but the tip is curved just enough
to get in between the pins and they are sharp enough to cut through them.

OK, as I said to Phil I've got everything but the curved tip, and I think
that should be fixable. ;)

Yep ;-)

Not that I normally bother, most times I can remove IC's complete with
the desoldering gun.

My DIY desolering iron project that I mentioned here fell in a heap when
the PC power supply which I had built everything around decided to die
during the final test (I don't think it liked the uneven load). I'll get
back to it eventually.

I shelved a few projects but have recently been getting back to them.

Actually, I think you have an 8255 in your possession that is testament
to that ;-)

Ahh, well I never quite had the heart to tell you that it didn't work.

Don't hold back, I can handle it :)

A strange, seemingly internal, problem where it wouldn't go into all
of its programmable modes. In the end I found some being sold for a
good price on Aliexpress and one of them got me working. Recently I
was even given an old PCB with a socketed one on it! Thanks anyway
though.

Sorry about that, I knew I should have sent two because there is always
a risk vintage stuff doesn't work and I couldn't test it. I would have
been happy to send another not that it matters now.

I gained a few more myself since and a socketed 8085 processor... one
day I'll do something with it.

We only have a Jaycar agent in town so if I need something the same day
they are my only option, otherwise it's a wait to get it from Perth or RS.

I've never had any of the stuff that I've bought from Jaycar fail. I'm
only in it for myself these days and if I want it, I want it now (or at
least within the hour). Ordering from RS may get it today or more
probably tomorrow, from the others it will have to come from Sydney,
best estimate 2 days maybe more. Lifes too short to wait that long.

You are very lucky indeed then. More than half of the last half a dozen
things I bought from Jaycar failed - some taking connected equipment with
them. For me the 'conveinence' of Jaycar will never again be put ahead of
the general low quality of their stock. This even though there's a Jaycar
store 5 minutes drive from my home and any other option is 24 hours mimimum.

**"Snobbery"? No. Here is ONE of my many experiences with their rubbish:

Back in the mid-1990s, I ordered and received 500, 15VAC, 300ma
plugpacks for a job I was commissioned to do for a client. Their pricing
was pretty good (around $5.00, I think). After a short time, failures
began. I scrambled to find an alternate supply. Telectran in Terrey
Hills, Sydney quoted me on an Australian made replacement. $14.00 each.
My client agreed, so we pulled all the old power supplies off the market
and replaced them with the new ones. The Jaycar supplies registered a 7%
failure rate within 3 months, before they were removed from the market.
In the four years after the replacements were supplied, I registered a
total of 3 failures out of 500 power supplies.

It just goes to show that some people are happy to pay for a bit of
quality.

That said, I recognise that a professional's requirements may be
different to a home user. For a professional, a component failure can
have far-reaching effects. For an amateur, it may just be a nuisance.

Almost all the plastic body solder pumps I've had were crap.

Years ago I found a turned aluminium one in a tool box someone dumped at the
recycling place.

Its pretty good - but I can't find any markings to identify the
manufacturer.

Do you have a trick for cutting the pins? I can never get any of my side

The pressed (and hardened) steel Excellite cutters seem to do the job, or
you can set aside regular cutters that have been ground for a slimmer point.

You can shear the pins off most SMD chips with a Stanley knife - but you
have to be dead careful not to slice through and hit any tracks underneath.

However, when you REALLY want to desolder stuff, this is what you

WES can supply. It is a beautifully built desoldering iron, which has
saved me a great deal of time and money. Damage to PCBs is minimised
with this device.


** I need to remove some 16 pin DILs from a triple layer PCB ( ground
plane in the middle ) while not damaging them. So far, only pin
cutting
and tedious removal of the each legs is working for me.

Do you have a trick for cutting the pins? I can never get any of my
side
cutters in close enough.


**Look for 'flush cutters'. That said, a credible argument can be
mounted to suggest that cutting pins after soldering is not a good idea,
as the stress of cutting may cause a fracture in the joint. Unlikely,
but possible. Best to cut first, then solder.


**Oops. Ignore that. I mis-read your post. A good desoldering iron will
do all you require.

Actually I usually try to cut pins on chips when I'm trying to isolate a
fault and don't want to cut the PCB (or veroboard) tracks. A bit of
component lead is soldered over the break after I'm satisfied. I have
managed it sometimes, but with great difficulty.

Cut tracks with a scalpel held at a sharp angle so the cut edges overlap.
flat it down after with the iron tip - it doesn't take much solder to secure
the join.

This is unsafe. It self-disassembles in use, projecting the
handle sharply upwards towards any vulnerable body part, with
the eyes being the most obvious targets.

Sylvia.

I've seen similar devices in use for the last 50 years and have
never known anybody hurt themselves with one.

Probably because the devices they use don't self-disassemble the
way this one does.


**Stop supporting Jaycar. I did. I've been much happier. Use a
proper supplier, like Element14, RS Components, X-ON, or even WES.

From where I live its 20 minutes to Jaycar, 40 minutes to Altronics,
over an hour to RS, the others aren't in QLD so a day or maybe two.

So its usually Jaycar if they stock what I need.


**RS offer free delivery and Element14 have a temporary free delivery
option right now. For my part, I'd rather pay the $10.00 ~ $15.00
delivery charge, than waste a 40 minute round trip to buy rubbish.
Life it too short to support some rich guy's Ferrari fetish, by
buying junk that fails quickly.

I've never had any of the stuff that I've bought from Jaycar fail. I'm
only in it for myself these days and if I want it, I want it now (or
at least within the hour). Ordering from RS may get it today or more
probably tomorrow, from the others it will have to come from Sydney,
best estimate 2 days maybe more. Lifes too short to wait that long.

You are very lucky indeed then. More than half of the last half a dozen
things I bought from Jaycar failed - some taking connected equipment with
them. For me the 'conveinence' of Jaycar will never again be put ahead of
the general low quality of their stock. This even though there's a Jaycar
store 5 minutes drive from my home and any other option is 24 hours
mimimum.


**You are a smart man. It is just not worth dealing with Jaycar for
anything more sophisticated than nuts and bolts. Even then.....

Sounds as bad as Maplin in the UK.

Some of their stuff works - but every time I used their mail order; they
sent the wrong type or quantity of parts.

They have been known to put faulty returns back on the shelves.

The lab power supply that I got from there is still working OK and the
resistors, capacitors, switches, connectors etc from there have worked
just as well as from anywhere.

I do believe that there is an element of snobbery in those who put them
down, their stuff is probably not the best, but it is adequate. Their
main problem is that they do not carry the range of stuff that RS etc
do. I buy a lot of stuff (where it isn't urgent) from China and nothing
from there has let me down either.

**"Snobbery"? No. Here is ONE of my many experiences with their rubbish:

Back in the mid-1990s, I ordered and received 500, 15VAC, 300ma
plugpacks for a job I was commissioned to do for a client. Their pricing
was pretty good (around $5.00, I think). After a short time, failures
began. I scrambled to find an alternate supply. Telectran in Terrey
Hills, Sydney quoted me on an Australian made replacement. $14.00 each.
My client agreed, so we pulled all the old power supplies off the market
and replaced them with the new ones. The Jaycar supplies registered a 7%
failure rate within 3 months, before they were removed from the market.
In the four years after the replacements were supplied, I registered a
total of 3 failures out of 500 power supplies.

It just goes to show that some people are happy to pay for a bit of
quality.

That said, I recognise that a professional's requirements may be
different to a home user. For a professional, a component failure can
have far-reaching effects. For an amateur, it may just be a nuisance.

How about another example?

Almost all the plastic body solder pumps I've had were crap.

Years ago I found a turned aluminium one in a tool box someone dumped at
the recycling place.

Its pretty good - but I can't find any markings to identify the
manufacturer.

Does it look like this?

I think I still have the one I bought from Tandy 30-odd years ago
somewhere, not that it was any good.
