We have this Robot. We have the large table model from Fancort. We have incorporated the machine into a process where it finishes up the through hole soldering that the selective soldering machine cannot reach effectively. About 2200 joints done wit

Small paste deposits have less flux thus less flux activity to enhance the wetting. So preheat needs to be as short as possible, ramp to spike if possible. Try not to ramp hold and spike - pending thermal delta on product can be made to ramp to spike

Are we talking a professional device that takes something like the Squink/Voltare/EX1 projects on Kickstarter and delivers something that could be confidently used commerically? Would it be strictly a prototyping tool or would it also be suited to lo

...Unless you could dispense a fine glassfibre mesh in much the same way a 3D printer extrudes plastic filament and then spray epoxy over the top. It would be remiss to 2nd guess what compounds physical chemists can come up with for such a project. E

Hi, I have faced some problems with DQFN PACKAGE 132 PIN. After some cross sections and dye pry analysis we could find a head on pillow situation always on inner row pads. The PCBAs are double side and the DQFNs are assembled on Bottom side (Noteboo

Dendritic growth is always a result of three combined factors: Conductive/corrosive residues Electrical current Moisture A wave solder process normally applies a higher volume of flux than a printed process. Flux however is not the only source. F

Cheers Rob, I thought that I wasn't far from the true answer....I figured that if we were to use a "first piece assembly " quote to get a first off through smt production, This would include start to finish process....e.g Programming to first board

Sr. Tech, you are right in that there is no verification of the profile. We are a Class 3 high mix OEM. We have visual inspection after SMT. We have not seen problems with wetting, grainy solder, cold solder, charred boards, etc. that would indicate

Thank you for your prompt response. The boards we have made for us current are Immersed Gold treated because we have been hand soldering and needed flat finish that would solder ok without tarnishing too quickly. I will take a look at the link you pr

Proc My field service back ground included Electrovert so I know reflow electrical quite well. I've worked on Heller, Conceptronic and Vitronics over the last few years and really there isn't a huge difference if you can read a schematic. I checked
