YES to the first question in some points of the board. Bulky, to the second question when it is not in short. What you say about the PAD height, helped me to understand why the SPI shows weird values for other measurements. I am currently doing test

We recently got a batch wash machine that can use a chemical cleaner. (not a saponifier). NOW I feel confident cleaning no clean boards. Without a machine that can heat water and use a proper cleaning agent, I would not trust cleaning no clean boards

I've never placed one of these before, but it looks like a poorly designed part. It has pads scattered asymmetrically around the body of the part. when it reflows this is going to apply uneven forces to the component, causing it to skew. I guess hav

A few times I have had success limiting movement in the oven by splitting up the paste apertures. In this case it might work if you had three bricks perpendicular to the leads.(maybe more) The trick would be making the gap between them big enough to

Hi, I work for a Cable and Harness contract manufacturer. I have started offering soldering classes to some of the employees but because we do not build circuit boards, I don't have any material for them to practice with. I was able to get a few ba

The followings may be the factors from your description: 1. chain speed and motor speed? 2. is the tin content even? (more or less on one side, or thickness of steel mesh, size of opening) 3. Is there any exception in the pin? 4. is there any level

This problem frequently becomes an issue with lead free solder paste, because it has very different rheology than leaded pastes. While not a 100% of the time, the squegees are very ofen the cause. When the regular blades are used (steel squegees), th

We had a selective solder installation tech raise the connector body off of the PCB slightly with a spacer to allow for a visual inspection to verify the process/profile. A few years back we invested in a large enclosure X-ray with a manipulator arm

we never used a paste of this type...not everything in the paste type and profile..Everything has an impact on soldering quality and sensitivity of materials quality and type of pcb...atmosphere and nitrogen in oven...Try step by step to solve the pr
