APPLICATION: SMT CARRIER TAPE FEATURE: �� High efficiency: joining is accomplished without shutting off the machine. The SMT machine can increase output 5%-15%. �� Reducing SMT machine and feeder abrasion: There is no need to unload & reload feeder

Our solder irons are tuned to 700*F, but the in-use temperature varies according to the solder alloy and the characteristics of the board and components. Check some of the papers on multilayer ceramic capacitors. They get fairly specific, for insta

Ben- My understanding of Tacky Flux is for Automation process where the Tacky Flux helps hold the component in place. If you are using a rework system that holds the Board firm..then typical no clean flux (Flux Pen) should work fine. I can only asum

Watch your dwell time especially if larger components. Problem is normally associated with lower temp as well as insufficient flux coverage with larger massed boards or ground planes. Try to hand spray a board to check that fluxer operation is OK. If

You have received some great feedback so far. I would like to summarize and add a few points regarding maintenance. You should start (as recommended already) by verifying your component library data. Using the default values from the master library i

Do you happen to know where I may find a supplier for the "little mirror"? Google didn't produce relevant search results for Mentor. My method of inspecting possible bridging under a BGA involved a small flashlight placed up against the edge of the

I am pretty happy with my Ersascope, they have been a little slow with software updates and with software questions that i have had. But my main reason that this has paid for itself is dealing with our non-local contract manufacturers, we have used t

The second one is typical. The important temperature is the temperature of the joint, not the setting of the oven. The oven setting are only important because they determine the temperature of the joint. If you set the oven to 150, that will be th

This may make it easy, Do you really need soak? Or can you just ramp to reflow. Most pastes that I am aware of perform just as well using the linear ramp as opposed to the ramp/soak /spike. Now, out of curiosity how are you attaching the thermocou

Orrrrr, just buy a small reflow oven, 5K to 7K, and eliminate the paste printing by using solid solder deposition. No shorts, no opens, no cleaning, and no voids. www.sipad.com If you decide to print your own paste later you can invest the extra 30
