on the top of your screen there is a search area. Punch in Voids and hit enter. The first discussion covers the voiding issue very well.

Hi I'read in last month Elektor about it. Some manufacturers own a soldering stations containing pipes tightened on the top of the solder in order to inhal the lead air. Looks interesting Maybe there something on their web www.elektor-electronics.co.

For flatness - Put the part on a leveling plate and roll a dial indicator across it. The leveling plate is not required for a true flatness check but using this will also work for parallelism of lead base to top of body.

I think realistically any speed quoted by any manufacturer should be down graded to 80% of what they quote. This should be used as top end, then the component, feeder count and complexity will start digging into this. As for achieving 75% of book spe

Does anyone know of a better way to inject grease into the cam follower bearings on top of the turret on a CP43? Fuji wants you to use a plastic hypodermic syringe.(It works, but it is kinda a pain in the a$$)

Just a thought, Solder flows to leads of parts and will tend to flow to hotest point. Im not shure but top side temprature might be hotter than bottom side. wouldent this cause solder to pull further up lead after leaving wave.

We had same problem. Solder balls appeared on top side of board and led to damaged second side stencles. We worked around problem by running blank boards thru oven and inspecting and removing solder before processing boards with parts.

I've never had one "float" in the wave. Have you tried waving yet to see? Anyway, glue would work, or you could place a a small weight on top, or clinch a couple of leads. Russ

I would highly recomend an 8 zones (top and bottom heaters) oven as it has better flexibility than 7 zones. However, I would also would like to check for the heated length. Some oven has many zones but the heated length is small. Arman
