hi everyone, I have done with my PCB Prototyping. I need to Prepare a Bill of Materials(BOM) for my PCB Assembly. I have one doubt regarding selection of SMD Capacitor. -My Question is For Example, I have to use 0.1uF capacitor on my PCB board.In

I'm involved in backplane manufacturing process. There are about 10 electrolitic capacitor assembled in my board.These capacitor are soldered using a selective soldering machine. My problem is that these capacitor will charged up and failed as short

Can someone please advise me to the rework procedure for removal and replacing Ceramic Chip Capacitors (e.g. 0805, 1206, etc.)? Is it necessary to pre-heat ceramic capacitors before soldering them onto a PCB with a soldering iron? Is this just a rec

Has anyone had any experience with thermal shocking and cracking of SMD capacitors during the rework process? My company was advised to preheat capacitors to 125 C at a rate of 2 C/sec before replacing them onto boards. Would this maybe degrade c

I have some questions on this. What is the power rating of the power supply? In power supply where are you using the capacitor? What type of loads you connect to the power supply? If it is a simple 50Hz rectifier, There is no option. You have to us

Brad, This is a common problem and may relate to the design of the board. In all cases when a device such as a capacitor is place near the edge of the board and the board must be de-panelled, the capacitor must be parallel to the break line. If the

Takfire Questions are: * Why does your customer think the capacitor is the issue? [What are we thinking? Of course the capacitor is causing this voiding problem. What else could it be?] * What are the type, construction, end-cap material and plati

On the dendritic growth over the top of the capacitor: We agree that your capacitor supplier probably did not do a very good job of cleaning process residues from their device. On the metallic fragments under the capacitor: This sounds like solder
