Sorry Michal I didnt get that. Do you think that they can be something else other than RS232?

As a project I am trying to design a circuit that transmits data to the 9 pin serial port (RS232) of a standard PC. As a basic start I am trying to make a circuit with 4 ptm switches, when I press switch 1 I would like to display "switch 1" or some

Michelle, It's been years since I worked on these machines and mine were CS400E's. The next time this error comes up instead of powering down Unplug the RS232 cable that links between the PC and the processor board in the machine, I cant remember if

As part of an Intel erratum, they changed their BGA coplanarity spec from .006" to .008". The package is 23 X 23 partial array, .050"(1.27) pitch, 1.220"(31) square. We apply paste onto BGA pads with a 6-mil stencil. From a process perspective, sh

Before changing solder pastes or jumping through too many hoops, check the melting point of the 100 Sn (pure tin) connection. According to Kester, the melting point of 100Sn solder paste is 232 degrees C. If you do not reach that temperature, you wi

Have you considered the plating of the component could be Pb free as this generally wont be liquidus until 232C typically. seeing more and more of these unmarked components coming through so worth checking latest batch of problems on unmarked QFP's a

We used to use 260+-5C (500+-10F) for Sn63, now we use 240-260C (460-480 F). You probably could get away with 232C (450F) in all cases, since there is no thermal mass to a lead being tinned. We keep our tinning temperature the same as our solder po

We used a company who wrote some software for us to do off line programs and storage, we utilised the rs 232 port to do this ,but this company went bust. TDK supply an MFT system which is expensive, I acn make some equiries for you from a contact at

Hi All, could anyone advise me what we need to pay attention to if we will be usingthe Sn Pin plating as lead free requirement in SMT reflow process, is it a need to increase the Temp Profile by 10~15 Degree c as Sn with Melting ppoint 232C, Please
