Hi Juan, I think if you check your Solder Paste's Data Sheet, you will find that your Solder Paste can be stored at Room Temperature for up to four weeks. There is no need to put your paste back into the refrigerator after every shift. If it makes

Both pictures are from .031" FR4. According to my MOLE it's actually staying above the liquidus temperature for close to too long. Datasheet says 90 secs, I'm in the high 80's. Not ruling it out as a possible cause, I suppose the data I'm getting c

Hello Rob, I was able to get the machine to zero, apparently replacing the circuit board on head 2 conflicted with head one even matching the jumper settings to the old board. Once I marked the head as not mounted, head 1 zeroed. I re-checked the ju

Hi there! If they are just standard headers there's a company called Teka that makes headers and socket headers with solder preforms in them. They call it "Solder Bearing Lead Technology" You can drop them in the board and reflow them just like SMT p

I am looking to test our Pick and Place robot with a RLC circuit of various sized components and orientations. I figure this has been done before, so before making it my self I wanted to check if such a board was available. Also, if there's a circu

Not sure how anyone could pretend to "ballpark" a cost for a board, regardless of size, especially in small quantities. You might need 10 assemblies, but the MOQ for your main component might be 100, 200, 500, 5K pcs. Makes me laugh every time I

Apply the correct amount of paste for the pad size should work ok, as long as the part starts out in the paste. If you have a reduced aperture and the leg doesn't quite touch any paste could result in non-wetting or insufficient solder issues. I gu

Using a vapor degreaser with a solvent such as Vertrel, Novec, Techspray 1655, Solstice, etc. may work for you but solvents can attack certain plastics. Should be fine for SMT though. This is assuming you are using a no-clean (RMA) type flux, not wat

We are required by AS9100 to keep expired material/chemicals off the floor. Examples include solder paste, flux, adhesives, conformal coating, etc. We have a system in place to prevent such occurrences but once in a while something is not accounted f

We are using Metcal STTC-8xx series tips. One thing that makes a huge difference on tip life is what type of solder you are using. If you are soldering with lead (SnPb) solder the tips will last 3 times longer on average than if you are soldering w
