Or you can use the Hot Air (Hakko) to remove that component and a tweezer to pull it. dont pull it just yet. If you see the solder melting then feel the component using the tweezer by wiggling it a bit and if you can wiggle it only then you can pull

In both cases, it will depend on storage conditions, unless you do something horrible to them (or as previously mentioned, wash them) months & months. For boards we put through SMT and then stash for THT loading in smaller qty's I don't think we've e

It's nice to be able to do things in house, and it's good to have somewhere without commercial pressures to learn and make mistakes, so I can understand where you are trying to go. Those machines look a little lightweight for consistent quality pr

Ralph, Typically our co-op students put down solder paste with a syringe, place the parts on the paste with tweezers, and then reflow the paste with a hot air pencil. This works pretty well when they are hand building prototypes. You can probably

Hello All, My first visit here. I own and operate a small Industrial & Consumer Electronics Service Shop. There is more and more modules with high density fine pitch SMDs that we cannot handle. We bought PACE ThermoFlow BGA SMD station with a bunch o

Sam We install a lot of die in the SMT room using same process as SMT parts.Water soluble solder paste is used for attachment of die to ceramic and boards. Biggest problem i found is the adjustment from installing the die in the bonding area. The t

Lots of small parts, lots of hand soldering, lots of tired eyes inspecting on lots of boards: yields lots of room for error. How about this: * Part removal ** Cut each resistor between the pads using dykes ** Using a soldering iron [or hot air pen],

Prof. Whoopee - amazing facts that you find on your 3-D BB, it has completely confounded my comrade, Chumley. Plainly spoken that around the SF Bay Area a.k.a. Silicon Valley(ever hear of the famous SF Fog?)during the winter months, near the coast a
