Cheery disposition??? Would a few ;-) ;-) ;-) help? [Oh and look who is talking, the one planning the Mickie D gig after the traces on the this board start vaporizing with the fuseable link schtik.] Are you sure you're getting flux all the way up

G'Day All, I have a couple of new Panasonic MSR's. Whenever I load a new program into the machine, I have to manually feed the first PCB onto the X/Y table to get it to run. After that, they run just fine. Panasonic is going to be in and they hav

Just talked to my component engineer. We use the B parts also, and apparently the B suffix indicates compatibility with wave or reflow applications, X is for reflow only. Since we only reflow these parts, sounds like that might be the best route fo

I wonder what kind of equipment the board designer had in mind? Are you shure you can do the board with a Mydata ? Where do you put the tray for your 20 mil QFP's? 10 mm thick plus component height also appears to be a problem. Multitroniks can do la

Hi Steve, Our China plant is using DEK 288. The cycle time is very impressive. However, there are some imperfections make our engineers feel bother. Maintenance is a big problem. As the machine was discontinued, the immature design was not improved.

The more we talk about this, the more it seems like you should use the process we've discussed to proof your design. Immediately there after, you should use a top-flight high-mix contractor to continue the prototype run for you. If you don't have t

Hi, And thanks for the advice. I have tried your method now, and it seems to be working. By visual inspection with a microscope it was almost impossible to tell the differrence between the pcb that had been in the frig and the pcb's that were normal

Assuming you're asking about double sided reflow soldering ... Use pad mating to lead wetting area. Bob Willis has found the ratio to be as much as 44 grams/sq in. Check Bob's site [Electronic Presentation Sevices] for more. Phil Zarro uses the

We have customers that are requiring no flux residue left on boards after soldering of non-water washable parts. We currently use Multicore Crystal 502 No-Clean to solder parts that are not washable. Has anyone come up with a good way to remove this
