We are having a bridging problem with SOIC 14,16 and 20 pin devices during flow solder of the bottom side of our boards. This bridging occurs about half way up the lead between the board and the body of the IC. The chip parts are no problem. The f

Wudduya mean ya can�t replace that ol� John Trieber? We agree. * Waverider thingies are best used to set-up process and in machine start-up. * Monitoring product characteristics is expensive, gives little information, and is so sloooow. [Plus we tu

The great thing about Mydata is the ability to put small strips of components on the Y-table. Takes only a few minutes to setup. I build mainly protos and small lots. The y axis is the table. The head is the x. Any problems you may have heard of were

Is it just certain locations on the board, or is it random, does it occur on every board, does this happen on any other products you have been running? If this occurs only on the 1 board and in random locations I wouldn�t say its your wave setup. I

We have developed a Cost of Ownership model that incorporates a number of factors when considering SMT equipment. There are the obvious ones like maintenance costs, labor costs and shift patterns. We also considere utilities, quality, set-up time a

80??? Whatever leads to you to that assumption? I'd love to see a study stating that. Based on experimental results at our facility, overvolume due to the screener parameters have rarely caused a solder short. so, in conclusion, does one need a solde

I agree with Dave. The only reliable way is to perform a time study using a watch with decimal minutes. Setup the study using an average rated operator and time 10 component insertions (from pick up to hands off), time 10 component soldering operati

Does the machine come with manuals, training? - do you get a feeder setup jig with the sale, is there any spares to go with it, do you have any contacts for spares, what sort of maintenance is required - how often etc. did the previous owner do the m

Hello, Can someone help me, I want to setup a high speed SMT line. i have only 3 different products, and i have to change only once a week. I want to place 0402 and maybe later 0201. I think that a FCM 2 or a QP-132E are good machines for that? c

I'd tend to agree with what the others have said. Check the basics, board supports, setup, wiper paper working correctly. If it's a humidity issue, try taking some paste, place it on a chem wipe, and roll it around a bit, which removes some of the mo
