If reference to Mr. Mike Gish's post. This article also references: "Thomson uses a very sophisticated software package that's both Interactive and dynamic, which allows the PCB designer to place insertable components correctly the first time, without wasting time on Checking all the parameters that govern autoplacement of components." Does anyone know of this software (company, cost, exact features)? Or is this software unique to Thomson Electronics? and No one else uses the below mentioned silkscreen technique?

Does anyone have any experience doing this? What is the minimum spacing that you found this to be effective? How hard was it to control the registration? Was this screen print applied in addition to mask webbing? What was the width and thickness of the screen print? Ditron Manufacturing speciallizes in PCB Assembly so you can imagine how helpful something this simple could be. any information you can provide would greatly be appreciated. What about using silkscreen barriers (Circles) around BGA pads? I haven't used this method in actual practice but appreciate the theory Talks in advance Mike Gish Sr. PCB Designer Ditron Manufacturing, Inc. ################################################################ DesignerCouncil E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c ################################################################ To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE DesignerCouncil <your full name> To unsubscribe: SIGNOFF DesignerCouncil ################################################################ Please visit IPC's web site (http://www.ipc.org) "On-Line Services" section for additional information.
