Little rubbery things
I was just inside my dropped-once-too-often Beckman 310 meter. The
display assembly is in pieces; it's a goner. But I am curious. Between the display proc and the LCD are two strips of flexible rubber that apparently are connections of some type. Can anyone explain further? |

I don't know what they're called but presumably an inspired idea by someone with no recognised credit. Sandwich of fine conductive fingers and flexible medium. Conductors perhaps 3 or 5 times thinner than the glass conductive traces or pcb lands. So can take up a lot of out of parallel movement, and misregistration as only one finger per contact needs to make any contact and mechanically isolates the glass from the pcb - Billiant! -- Diverse Devices, Southampton, England electronic hints and repair briefs , schematics/manuals list on http://home.graffiti.net/diverse:graffiti.net/ |

The commmon name is "Zebra Stripe Connector" for obvious reasons. The original poster won't have problems with these anymore, but most of us haven't been so lucky. --- sam | Sci.Electronics.Repair FAQ Mirror: http://repairfaq.ece.drexel.edu/ Repair | Main Table of Contents: http://repairfaq.ece.drexel.edu/REPAIR/ +Lasers | Sam's Laser FAQ: http://repairfaq.ece.drexel.edu/sam/lasersam.htm | Mirror Sites: http://repairfaq.ece.drexel.edu/REPAIR/F_mirror.html Note: These links are hopefully temporary until we can sort out the excessive traffic on Repairfaq.org.

By-the-way, Beckman sells replacement parts for your meter. They can also
service it for a reasonable rate. -- JANA _____ "Mistress" wrote in message . .. I was just inside my dropped-once-too-often Beckman 310 meter. The display assembly is in pieces; it's a goner.

Not sure what the rubber strips are without seeing them.. I hate to be opertunistic and perhaps you can get your 310 up and running again. But if you do decide to take the plunge and do some meter shopping. We have a wide range of DMM's do you have special requirements? True RMS, serial port, componant tester etc...

They probably consist of bands of conductive rubber separated by bands of insulating rubber and make connection between the circuit board and the LCD display. It is a bit hard to solder to glass but you need to get the voltages to the display somehow. -- bz 73 de N5BZ k please pardon my infinite ignorance, the set-of-things-I-do-not-know is an infinite set. remove ch100-5 to avoid spam trap |
