Hi, I think the standard was IPC 6850. But I will recommend to go directly with the sigma test. Place parts with the machine and measure the placement accuracy on another machine. 4-5sigma at 50um should be a good machine. If they have sigma in thei

I tested original 'bad' SRX card in the other machine and it doesn't work, same error: SRX Autobaud Motor error #5 With our QUAD 4C, (Machine speed setting) MC 53= 0 (high speed), I changed =1 (low speed), same error

Shear tests are [in my opinion] senseless. The shear stress you measure depends more on the shear rate and on the point where the force is applied than on the grain structure. When shearing a component, you not only apply shear stress, but also roll

Louie, We'd be interested in your experience with the stainless centering jaws. We just ran a job with heavy 0402 placements, and had a rough time with it. After much work on the package, magazine centering, etc, I've concluded the issue is the ce

hello Vikkaraja, your machine failed to pickup & centering test refuses to stop because the machine cannot determine which Head is currently at which station. on Head A, there is this little "dog" that cuts a sensor somewhere at station 9 on your ma

With zero knowledge and no internet degree on 3D printing... It seems to me to be a good use of the tech. I envision some CAD design work, "printing a sample fixture", testing it for fit, then sending the CAD file downstream to a CNC machine. Somet

Do you watch when it is doing the wave height test? Watch it and see if it goes up to the same spot on the test probe each time. If the test probe is dirty sometimes the solder has to go up higher on it before it gets detected. You might actually be

Hi everyone, We started our first machine placed shield test today.We will be machine placing shields with in the next two months. I used a Fuji Qp242 today. There were no problems with pickup etc,. just vision errors. I'm sure we will work them ou

A long time ago, in a place far, far away, I would test Fuji IP machines without the MFU's installed. They have a mechanical switch on the machine so it knows when a MFU is present. But what normally catches everyone is that the locking air cylin

Hi, I'm from a semiconductor package assembly, and currently looking for an offline solder paste inspector capable of true volume measurement. Any recommendation for a machine that can measure paste volume on a leadframe (metal substrate)? I found
