Re: [Ql-Users] Q60 aging problems

Hi, I would be careful desoldering a PLCC chip, the D  Q60 was soldered correctly under the correct soldering temperature.  I have repaired some Qbranch Q40 boards, which had issues with the over heating of the soldering, resulting in detachment of the through hole plating. Regards Derek

Re: [Ql-Users] Q60 aging problems

Assuming the PLCC has a through hole socket, would it be possible to solder a pcb carrier for a more modern chip on the back of the board using the PLCC pins that protrude through? On 11/03/2016 22:17, Peter Graf wrote: Am 11.03.2016 21:48, schrieb Thierry Godefroy: On Fri, 11 Mar 2016

Hi Thierry, The Q60 / Q40 clock chip is a ST M48T02-150PC1 Timekeeper battery. It plugs into a 24 pin socket on the Q60 board. It is still available, if you need a new one I will source some. Regards Derek -Original Message- From: "Thierry Godefroy" Sent:
