Batch Cleaner Closed Loop YES!!! / NO!!! / MAYBE???

Electronics Forum | Fri Feb 15 13:24:44 EST 2002 | Mike Konrad

Hi Dave, To close-loop or not to close-loop, that is the question� I can not speak for all machines, but in our case, close-loop systems are actually less costly to operate than open-loop systems (we make both). First, determine the volume of wate

Wave solder question

Electronics Forum | Tue Feb 19 14:00:55 EST 2002 | global

We have had some discussions about what causes parts to lift out of the holes when going over the wave on our flow solder machine. The machine being used is a Treiber (700 series). There are two bottom pre-heaters and one top pre-heater. We try to pr

Wave solder question

Electronics Forum | Tue Feb 19 15:59:55 EST 2002 | pjc

Surface tension is a likely cause. Surface tension is a negative wetting force. You may have a solderability problem. Be sure your flux is properly activated according to the flux mfg. top side board temp. specification. When surfaces to be soldered,

Networking Panisonic SMT Equipment

Electronics Forum | Mon Mar 04 18:25:21 EST 2002 | Jones

I was wanting to know if anyone has had any luck at networking Panisonic equipment. We've purchased the Panacim package for one of our lines and have found that it was very costly and can create downtime. We are wanting the capability to download mas

ROI on AOI Machines

Electronics Forum | Thu Mar 07 12:33:39 EST 2002 | peterson

We are currently examining the issue of AOI machines (both in-line and off-line) It seems that the only positive remarks I find are written by the salespeople representing AOI manufacturers. Can someone please refer me to a more neutral source? My in

Time to get out

Electronics Forum | Thu Mar 21 00:01:46 EST 2002 | jbutile

Can anyone give me a good reason to stay in this industry. I really do not want to be the last one in this forum while I see all my friends move on to other jobs, reasonable pay and security. From all I can tell it is over, there is nothing left to

Buying Used High Speed Equipment

Hi, Just to ease your mind a little. I have 15 years experiance on Fuji kit, and was the engineer in charge of over 30 CP6's. They are very robust and the electrical / electronic side is pretty bomb proof. The main thing to look out for is wear in

BCC Technology --- Placement, Rework, Reflow

Electronics Forum | Mon Mar 25 13:48:52 EST 2002 | bcceng

We are currently applying solder bumps to hundreds of BCC's for rework. It is impossible to print to the PWB. It is recommended to apply solder bumps to the BCC's with 63/37 alloy making the rework faster and easier. Applying the solder bump on the

Stencil Cleaner

Electronics Forum | Thu Mar 28 13:25:43 EST 2002 | Mike Konrad

Hi Dave, No-clean paste is more difficult to remove in post-reflow cleaning applications. In stencil, misprint and tool cleaning applications however, no-clean paste poses no extra degree of cleaning difficulty. There are few special requirement

What is too much silver in a joint

Electronics Forum | Mon Apr 01 07:41:40 EST 2002 | davef

Hey Bob, Boy, you are lucky to have a laboratory, and now colorful pix!!! The only silver IMC that you will see are: * Ag6Sn, much less likely at 'normal' soldering temperatures * Ag3Sn, much more likely Allowable silver concentration: * Below 2%
