First, I would inspect for lack of solder bridges from the center slug to the outside leads. I would then look for evidence that the solder paste has reflowed beneath the component, without leaving too much void percentage. Typically we allow up

Hi All, Does the Inspector software have a library manager? I see a "Standard" and an "Alternate" library folders. The standard library shows the outline (like a footprint) for the components but the alternate library has pictures and outlines with

Does someone with technical knowledge knows what exactly happend with the solder paste after the shelf life pass? What we have seen is sometimes flux separation which disapear after a good mix, and change of viscosity i.e. drying. The tin, silver and

You are very right. There are 2 major factors 1) There is going to be Flux separation. This is basically due to fact that metal particles are heavier than the Flux vehicle system, and due to gravity effect they slowly drift downwards leaving the ligh

PKannan, Your opinion is contrary to J-STD-005 "Requirements for Soldering Paste". Within that document is included specific requirements for re-certification of expired solder paste. Paste that is expired can be used after a simple viscosity test an

I don't remember seen any settings for the marker in the board options. But then again I can't remember where the board options are. I haven't turned on the machine in like a week. I haven't really checked if the marker moves when I zero the machine

Hello all! Here's my issue: I've been assigned to make a programming fixture for a contract product we've been making. We're ramping up to 300+/month so it's becoming necessary to have more permanent fixtures. Usually, when programming, we have a

You can contact IDI directly. Also try QA, they are a little cheaper in price. .050 center probes are not uncommon and should work for your application. Both may have a minimum order of 200 pieces or so. I don't know what Mouser's minimum order a
