• Manufacturer Part Number: ch1840
• Description: Profile Data Access Arrangement Modules
• Manufacturer: ETC-unknow

Mounting the CH1840
The CH1840 can be soldered directly to the host circuit card or
installed in sockets. Direct soldering provides the most sound
connection. To avoid the problems of flux contamination, hand
soldering is preferred to wave soldering. Many socket manufac-
turers offer socket strips that accept the 0.025 inch square pins
on 0.10 inch centers. When using mechanical sockets, restraint
of the CH1840 should be provided to keep it seated during ship-
ment. Plastic cablewraps are secure yet easily removed.
