| Anyone using SMT "Fair-Rite" beads? We have a P/N 2743019447 that we're using. We need to know the shear force strength of the part and the vendor's man who knows is in Deutschland and can't help until Monday. I can't wait that long. | | Also, do

| | | Scott: Where is the problem? When you have a board in one hand and a sheared ferrite in the other, what does the ex-ferrite location look like: | | 1 Green mask colored, because the pad is "ripped off" the board | 2 Gray lumpy looking, be

Pat: No, but if you describe the situation we may be able to sort through your soldering problem. Good luck. Dave F

We are having a lot of tomb stoning with this no clean solder paste. It's limited to larger, complex boards, affecting 0603 ferrite beads, capacitors and SOT23s. It was suggested that paste removed from a stencil should not be put back in it's origin

Hi, could any body tell me the reason for solder beads apperance and how to aliminate them (solder beads are solder balls that are found along chip body). Thanks,

Hi, There are 2 main steps to reducing EMI from a product. The first is to minimise it at source with smart design (keeping signal traces short, lots of decoupling etc). There should be design guides available from internet seach engines. Many ma

We have this solder ball & beads around chip components since day one of manufacturing using non-clean process. We managed to eliminate the solder beads around ceramic type chip componenets when we have a slow ramp up of pre heat at solder reflow. Ho

I am interested in getting some feedback on what different companies are doing to eliminate the solder beading issues on 0603, 0402 chip components using a no-clean process. We are currently incorporating a solder mask removal between the solder lan

Calvin, We have found several reasons for solder beading occurance. We have found that solder balling is usually directly attributed to the reflow profile while solder beading is usually (but not always) a result of either excessive solder paste volu

If you mean solder beads at the side of chip components then download the FAQs and the process guide on solder beads which may be of interest. The documents are on my web site www.bobwillis.co.uk | We are getting solder balls after reflow of surface
