Hi Jax, I didn't understand your question very well. I'll try to answer based on whatever I could understand! Most Gerber viewers available in the market - especially free versions, DONOT have the capability to group apertures to build component. T

We have been manufacturing a part using bright electrolytic tin as the finish. Our customer has been hand soldering using 63/37. They have recently switched to SN96 and have been experiencing solderability issues. We have sent samples to an outside

I understand what he means. But has he confirmed that an unusual situation is what is really occurring, or is what happens at every other company happening there? It is very common to have part droppage. Look at all the threads on the subject here.

Best to use Tin treated with TinP Additive. This ensures the Tin is fluid enough to Dissolve any Leaded residues. Run the machine for one hour at 275C then take out wave former and as much of the workings of the pot as possible. Then start bailing ou

Hi All, I just realized that our CP-6 is reading only two of three fiducials. Is this normal? The coordinates are not the same and they're numbered 1,2,3. We use the MCS30. I checked the proper data and I couldn't see anything that would cause it to

When we have sent some of motherboards for reliability testing in a tird party laoratory. It is found that when Dye&Pry is done after 600 cycles of Thermal Cycling, in LGA socket only one of the corner solder joing had 100% type 3 crack. All other so

Yes, the vias under the BGAs are the only ones capped. I tend to agree with you that the leaching should affect the bottom more than the top and that was actually the case with the two previous shops that had this problem. We suspected with those s

Thanks Pete B - great info. I am currently preparing a DOE to address concerns about reflow of componentry on the bottomside of the PCB while in the vapor. Specifically cosmetics and part dropping. Bottom side has no flux, but will be fully reflow

I am having some problems getting the IP1 to place a SSOP28 package,pitch 0.65mm lead width 0.3mm. I am selecting computer vision 012 (tried 011) and vision type 100. EL data was put in looking at the datasheet and also measuring the device. Have tri

We recently received in a reel of a QFP-64 TI processors. TI has such a great lead time right now, we were forced to find these parts where we could. Unfortunately you are forced to deal with less than reputable people. So these parts did not come
