Temps are related to the components/PCBs being soldered. I am not aware of any Industry standard. If you are soldering flex circuits, .020" boards etc.. We use 500 deg tips a little thicker PCB/lead we go to 600, and so on. We never exceed 800 in a

Dave, You stated that an unfilled via is of greater strength than a filled or partially filled via. I posted to another thread recently and I stated that a filled via was of greater strength than an unfilled. I was tought (incorrectly?) that a fill

I have a client interested in using a Toshiba Part P-TFBGA48-0607-0-0.75AZ. Mechanical data on the part can be found at: http://www.toshiba.com/taec/components/Datasheet/51WHM516AXBN.pdf I am concerned with being able to use this part with consist

we have recently been trying silver composition on our pads with our PCB boards. I am wondering what if any characteristics are different from tin etc... I have found with profiling the board it to be about the same temps. but getting granular looki

Hi Don't really know what "your grainy" means. It could be good, marginal, or bad. You need to get some photos or micrographs of what is normal and off-normal. Compared to Sn/Pb 63/37 on mostly Sn it should look visually different. Every time you c

How are these connectors and dips oriented? If the leads are parallel as opposed to perpendicular to to the wave this can promote bridging depending on spacing and length. The long leads showing icicling are most likely either inadequate heat OR the

Little off the topic of SMT production, but I am in urgent need of a 60db sma inline attenuator. Male to female @ 2.2-2.3 Ghz. Size is extremely important, I need it to be as small as possible(around 1 inch in leanth) If anyone knows where I can find

Hi I hope I am on point based on my reading. The outer edges bow spec depends on a gradual deformation that finally builds up to the outer edges. If you mathematically move this deformation back you will have allowable deformation at the point you

Your points are all valid. This is probably a service that the component distributers should provide. The reason I am harping on this issue is because I beleive is is possible to add several hundred part numbers to your pick and place on line inven
