So, what is the battery going to do when you push your 'high voltage' through the 1-2 ohm internal resistance of the 9V battery? How about you doing a Google search on ... esd protection circuit?

Hi We are experiencing serious problem with ceramic capacitors. They are with low electrical resistence and the problem is intermittent. We found some of them with micro cracks but not all. What could be the causes for this problem? We are su

Rich Here's what Humiseal says: Thermal Properties The coating must be able to withstand localized thermal 'hot spots' generated by components. High temperatures can cause short-term changes in coating characteristics, such as softening and lowered e

hi, I am looking for some guidelines which can tell me when gullwing and finepitch leads are too damamged to repair. Copper gets hard when bent and the electrical resistance increases. When a finepitch component gets dropped a lot of pins need staig

Hi I am looking for informations/specs about graphite/carbon deposited on PWB as a "spring contcat" or land (? not sure how to say in English). - Are there any Standards (IPC?)who define correct thickness of graphite ? - Are there any Test Method

Electric drivers are harder to adjust wich keeps production people from messing with 'em. Electrics are resistant to other variables such as air preassure, quality, other air supply users on the same line and so on. I prefered to use all electric e

Hi, I read an article that says "Flux selection usually depends on the following factors": a) Solderability of pcb base metal or coating b) Corrosivity of vapours and residues c) electrical resistivity of residues d) Ease of removal of residues e)

Steve, How do you measure the resistance is it by probing the surface? Concerning the alloy there is a straightforward linear correlation between the tin content and the electrical conductivity of the alloy. The higher the tin content in the alloy,
