Hi, We just bought 2 YesTech F1 AOI machines and we could use a little help. We are using Mentor Valor tools which generated placement files (.ycd) but we need to manage our F1 package and marking libraries. We will be doing a lot of very short run

Hi Rob, Thanks for the LED paper. I like the void area equations but I am puzzled, the paper did not say if the solder was a solder paste that would generate a lot of voids, or a fluxless preform or sinter material. The measured voiding level

Hi Adonys, What's ICP 1-3? Do you mean IPC? 1. Excess Plating- no excess, but filled with something which generated in the process of copper plating. 2. Dark Vias - it's oxidized. and the solder mask printing is not aligned. The board is failed. M

I agree with you. IPC Committee 5-24b Solder Paste Task Group is responsible for maintaining J-STD-005, Requirements for Solder Pastes. They generate "standards, test methods, and a handbook that reflects current practices in all aspects of electro

I agree 100% with you!! this was nothing more than a way to generate $$$$. the course was a complete joke! the person we contract to train our trainer and some of our ipc-620 folks thought the very same thing, she was very frustrated with it. we paid

Dear Sir, Sanyo Denki Bi-Polar motor rarely rotates with actual speed while Picking up the component, Otherwise Stepper motor rotates with very slow moving speed by creating noise and same speed variation repeats while Placing the component. After co

I managed to find a brand new old stock Novastar GF-12 oven for $250 (it was used once but you can't tell): https://milwaukee.craigslist.org/tls/6539855333.html This seems like it may be perfect for my needs. It does seem industrial grade but only

Minami vacuum reflow is easy to maintain air tightness, and oxygen can be reduced to 50ppm or less by filling N2 gas. And generation of oxide film can be suppressed, and production in low oxygen environment is possible. In addition to the air tightne

We don't have your exact machine or know your exact configuration, but our machine has occasionally gotten an estop due to a breaker in the SelectX tripping. Just be aware that there are circuits other than the mushroom switches that can generate an

We use eagle for PCB prototype design but it does not have in Gerber CAM scripts by default, when we export the Gerber, layer seems to be wrong place. I want ask you how I can do proper Gerber output for bottom silkscreen as long other layers (mask,
