Phil Zarrow: Kim, there are all types solder preforms out there. What exactly are InTEGRATED® preforms?
Kim Flanagan: Well, Phil, today I actually brought some InTEGRATED® preforms.
These are InTEGRATED® solder preforms. Basically, it is an array or matrix of washer preforms that are connected by solder strands that, when reflowed, wick away. It's a sheet that you can actually place onto a set of pins all at once rather than individually placing washer preforms onto pins. Saves a lot of time. It's more cost-effect. It's more manufacturing friendly.
Phil Zarrow: It's much more ergonomic that way.
Kim Flanagan: Right, right. Yeah.
Phil Zarrow: It's easier to do.
Kim Flanagan: It's more efficient. It's more manufacturing friendly.
Phil Zarrow: Right.
Kim Flanagan: Reduces labor costs and saves assembly time and so forth.
Phil Zarrow: They've come a long way, because I remember the days when they put individual donuts on each pin and such. That's not my idea of a good time.
Kim Flanagan: Yup.
Phil Zarrow: With regard to applications, we're talking about pins. First thing that comes to mind are connectors. What else might these be used in?
Kim Flanagan: Right. These can be used for any application that's got multiple pins or pads. For example, PGAs or pin connectors, and so forth.
Phil Zarrow: Right. Anywhere where we're trying to add a solder body and for intrusive soldering or pin-in-paste or whatever.
Kim Flanagan: Right.
Phil Zarrow: Of course this isn't pin-in-paste—this is preform-on-pin.
Kim Flanagan: Right, yes.
Phil Zarrow: Pin-on-preform. Okay. Along those lines, and of course, the interconnecting strand you mentioned is thin enough that we don't get bridging.
Kim Flanagan: Exactly, yes. It's thin enough so it's able to wick away from each washer, and you're left with an individual solder joint for each.
Phil Zarrow: Now, are these custom configured, or are they standard? What's ...
Kim Flanagan: We have both. We do have standard sizes and with standard alloys—your SAC305 and Sn63. Then we also have custom sizes that we can make as well.
Phil Zarrow: Kim, what information do you need to configure these for a customer?
Kim Flanagan: There's five characteristics that we would need to know. There's the pin diameter, the hole diameter, the thickness of the board, the pitch between washers, and also whether or not the InTEGRATED® preform needs to be staggered or if the washers need to be in line with each other.
Phil Zarrow: Where would we go for more general information on InTEGRATED® preforms, Kim?
