If you havent already resolved the issue. I would recommend running a wave profiler and see if you are actually getting the same thermal profile in each machine. Generally speaking you need to run different preheater settings for different brand wave

Universal Instruments AC30L. Rated at over 30k CPH but dependent on mix you will realize between 18k and 24k CPH REAL speeds. Very flexible with feeder cart swapping. Wide component mix. American made and the best support of any p&p company. Sounds

Hello all, does any body place PoP parts? We are running them through a regular process(paste place reflow) and we don't have good rates on these. Mostly we observe opens at the sides of the part. We are thinking to purchase a flux feeder, but I wan

I have a large monoblock ceramic filter on a PTFE based pcb material. The filter has a metal casing soldered onto the ceramic filter. I am concerned that if the heating rate is to rapid, then thermal shock / differential expansion could cause the fil

Our observation also is that the tape size is too big for the chip which allows the tape to move around. With this i would like to know if there is is a setting in the machine that would slow the feeding rate. We are using juki mounter 2000 series. A

Smaller companies many want to rent a machine, but may not necessarily use it 24/7, and a smaller machine may require less expertise to use. If many small machine can work fast enough, it can operate for less time and reduce operating costs. (I'm mo

the data collected from a standard SMT process is typically very noisy due to the natural.Initially, the most common evaluation method was placement yield.Offset Placement After Solder Screen-printing can reduce or eliminate these defects through cor

We have been experiencing an issue where our Panasonic film caps on a board are losing their rated capacitance. We are well within their recommended reflow specs and no other operation exposes the part to a temp of more than 160°C. The caps will read

The layer count itself isn't going to be what drives yields. What is the trace/space? How much annular ring for vias did you give them to play with? Class 2 or class 3? What's the worst hole aspect ratio? Controlled impedance? The closer you run to y

If an electronic component with a MSL rating of 1 is exposed to an moist environment greater than the 85% relative humidity to the point where the packaging is wet, what is the risk level of using the device in a lead-free soldering reflow process?
