wave soldering and solder bridge

Electronics Forum | Mon Dec 17 12:06:58 EST 2007 | pjc

5 Steps to Eliminate Bridges: 1. Establish (wave) Parallelism First and foremost, you must establish board-to-wave parallelism. This is the prerequisite to any wave solder process control. For an understanding of the power of this approach go to ht

No solder and solder bridge after Wave solder machine

Electronics Forum | Thu Nov 17 13:13:49 EST 2005 | Mike

Hello, Some questions.... Are you running lead free? What alloy? What�s your pot temp at? Temp of the board after preheat? Are you getting any solder in the barrels (

No solder and solder bridge after Wave solder machine

Electronics Forum | Thu Nov 17 20:51:16 EST 2005 | cangly

Morning Mike, We use Pb63/Sn37, Alpha Metal alloy. Solder pot is at 250 C. The profile of board after Preheat about 100 C, Lambda Wave about 220C (use both Lambda and Chip wave), DWell time 2.1s ~ 3s. Conveyor speed 1.5 in/min. We run by bare board a

Conveyors and bar code

Electronics Forum | Wed Aug 23 14:59:32 EDT 2006 | bill

I�ve been lurking on the forum for a while so I will take a stab at this, mainly because there is no answer I take it that you have a variety of boards being produced at the same time and are in fixtures so the conveyors don�t need to be adjusted, a

SPC and Wave

Electronics Forum | Thu Jul 14 11:52:16 EDT 2005 | davef

Sure you can use SPC charting on the wave setup parameters to warn of impending problems. Examples of useful points of analysis are: * Dwell * Temperature * Pot analysis Certainly there's a range of other process controls that could be monitored.

Selective soldering pallets and solder balls

Electronics Forum | Tue Dec 10 14:10:38 EST 2002 | Randy Villeneuve

Steve, I wave solder most if not all our boards with selective wave pallets. I did not catch if the solder balls were on top of the board or on the bottom but that will make a difference on what to do to get rid of them. Pallets are good and bad. On

Wave Cassettes and Heat convection

Electronics Forum | Tue Jan 16 07:59:36 EST 2007 | tk380514

we worked out that the wave soldering cassettes Duratstone material takes alomst 35 degree away from the surface of the pcb, and the speed is already too slow it should be over 1.0 - 1.8 meters a minute but its now already 82 cm a minute, in order to

Wave Soldering and Through Hole Forums

for regular eutecticish solders, keep the pot temperature between 230�C [446�F] and 290�C [554�F]. If you polled us on our pot temperatures, we�d be all over the map, but with more lower than higher than you. High pot temperatures tend to generate

Heat guns and component damage

Electronics Forum | Tue Jan 31 15:51:04 EST 2006 | russ

Relays huh? I can tell you from previous experience that relays are not a good heat gun candidate. Did you check how long this part can withstand the 240? I do not know what the 4 setting is on a liester but it is probably well in excess of the 24

Leaded and Lead-Free Wave Parameters

Electronics Forum | Fri May 23 18:55:20 EDT 2008 | gregoryyork

This is one of the biggest mistakes with the Lead Free process. We have all listened to the 'industry experts' and followed their advice and unfortunately got it wrong. Keep the dwell times (dependant on alloy selection) the same as Leaded so you are
