We do have in stock a pair of Panasonic Soft Beam Selective solder systems which use light to solder. They are practically brand new and seem to be ideal for applications where one or a few connections need to be soldered. They are even pass thru m

Electroplating [electrolytic] and dipping [HASL] are the two methods for applying solder coatings to features on boards. Disadvantages of electroplating lead / tin are: * "Weak knees" created at the edge of plated through holes. [I used to get weak k

We have been looking into some sort of higher level inspection system as well. But we have been fairly well convinced that X-Ray is far better than AOI. X-Ray is not only good for BGA's, it is also good for any solder related problems. AOI can onl

Cuppla questions for ya ... Where are the shorts [above the mask or between the mask and the laminate]? On the board, what material is between the copper traces and the mask? What type of solder mask(s) used by your suppliers? What are they using

We are currently investigating getting a small SMT line in-house...very low quantities. I have been looking at Screen Printers and have also stumbled across Solid Solder Deposit Technology at 2 companies. I'm not sure whether we want to have the So

Depending on the stress condition experienced by the solder joints. For joints under a greater stress, the time to reach equilibrium can be shorter. Of course, the change is also more significant in phase structure. For low stress conditions, it may
