A trick I used to use doing RF design was to have on the edge of a panel, a stripline that I could hook up to a Network Analyser to check board impedance. You could do this to verify if the fault is in the no wash process or a board manufacture proce

I understand the Camalot and Mydata both have a maximum board length of 20". How do you/would you process a board over 20" as mentioned you sometimes have 49" boards? If a screen printer is an option, have you seen the ESE US-LX3 which has a maximum

soldering a very simple board in a very simple Accuheat oven. Can anyone give me basic starting point settings (conveyor speed and temperature) then we will profile using a mole from there. Paste 1) Tin Lead Paste 2) Chipquik low temp TL 165C PR

All you have to do is to go on the floor when the machines are running and see yourself what the speed is. All machines show this data and even more. Most machines show some statistical data too - you can dig a little bit into that and you will get y

They are probably getting a little hot. So that leaves several courses of action. 1: Don't place them before reflow and hand finish. 2: Shield them with a little folded shield to decrease heat transfer. 3: Speed up the time through the oven, but th

We have been running a Heller 1707EXL for 8 years and added a Heller 1707MKIII about 1 years ago. We have not had any problems with either one of them. We do both lead and lead-free assemblies along with BGA/LGA components. If speed/volume is not

Very interesting question you have here. Guess where all the mass production id? -In China. Brazil is still a market for machines. Besides some automotive, US is not really doing mass production any more.

There are factors that manufacturers have taken into consideration when dealing with coating. On/off times, dispense speeds, heights, etc.. Dedicated software with tools to easily map out paths are a godsend. We made our own coating machine with a s

Bruce, I have different size electrolytic caps. Most of them should be no issue to pick 8 at a time(5-6mm) Can't I decrease the speed of the head when placing these parts? I would love to place slow motion 8 parts at a time than going 8 times with t
