Hi All, What causes the z tower to fall/slide down in this machine? There is a break at the bottom of the motor but the book says that it is for when the machine is off. It could happen at any moment. It sucks when it is in the middle of printing a

I am assuming this machine has a tactile sensor that mounts to the printing table. If the air connection or any of the wire connectors get under the rear rail it will cause the Z to fall. Also any bare wires on the tactile sensor that touch the prin

Hi, I am facing high fall out of microphone low sensitivity issues. This microphone is soldering thru SMT soldering with low peak temperature profile which peak at 232 DegC to 240 DegC and have skipped X-Ray inspection but still seeing fall out espec

Our company applies solid solder to surface mount lands. While processing a micro BGA design we had some pads fall off, peel, whatever you might call it, from the surface of the board when touched "GENTLY" with the tip of a blade to remove a small s

| WOULD LIKE TO DO RELOW OF 2 SIDED SMT BOARDS. USUALLY THE BOTTOM SIDE HAS RESISTORS AND CAPS ONLY. WHEN THE BOTTOM OF THE BOARD HEATS UP, THE PARTS ARE FREE TO MOVE AND ONLY SURFACE TENSION WILL KEEP THE COMPONENT FROM FALLING OFF. | CAN BOARDS BE

| I am looking for more information about: | | 1) What kind of evaluation can I do to measure the resistance to fall off of a bottom side glueded SMT component?; | | 2) There is some influence of doble wave solder machine (temperature, flux, etc) i

Has anyone had issues where bottomside double reflowed smt has fallen off in the wave when using voc-free flux? I have verified the hotter profile was not the issue by using an alcohol based flux with no problems.This voc-free flux is also not causin

| I have a component that is glue cured on the bottom of a pcb. The component is a 1206 size jumper. It is made up of iron/nickel alloy. The problem I am having is that the part will fall off the board during wave solder. Is the component not abl

Like most things in electronic assembly, this is not astrophysics. People have pasted boards, placed components, turned the board up-side down, run the board through a reflow oven, and generalized about which components: * Fall off the board. * Don

Hi You might be right that the ban will go ahead eventhough some indications, like the report from Germany, show it will be an environmental drawback. In Denmark I�m aware of 2 lead-free invetigating projects on the way. I participate in one of t
