Our supplier for epoxy sheet adhesives has significantly increased prices, and I'd like to look at alternative sources. We use this stuff for bonding ladder-style aluminum heatsinks to PWB's. The types that we use are either glass cloth or Kapton film covered with epoxy, total thickness from .004" to .009". We cut material on a programmable x-y machine that looks a lot like a plotter, but with a blade instead of a pen. Cure is with heat and pressure, either in a fixture and oven, or with a vacuum bag and platen press. We like dry film better than screen printing or dispensing liquid adhesive because it's a lot less messy, bondline thickness is very repeatable, material doesn't squeeze out when fixtured, and there is no smear when aligning the heatsink with the board. Anyone use Arlon materials for something like this? Other sources? --------------------------------------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8d To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt delivery of Technet send the following message: SET Technet NOMAIL Search previous postings at: www.ipc.org > On-Line Resources & Databases > E-mail Archives Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ---------------------------------------------------------------------------------
