We have a customer with an assembly that will require potting using 3M DP-270. There is a component that needs to be covered with potting material but it is considerably higher than the overall potting height of the cavity. The low viscosity of the

We have MY12 and MY15E machines. I am going to assume what we are seeing also applies to the MY100 series machines as well. Do you have the electrical verifier option that works with the midas head and centering jaws to check component values of

Hi everyone! I have P&P Quad IVc. The Hand Held Terminal (HHT)says "V idle" intead of "V ENTER CMD", and when it is running, the HHT shows commands lines each one at the same time it is running. One of our technician entered mistakenly, at the HHT,

I haven't used this particular CC, but...found this in their data sheet: "AVR 80 BA Conformal Coating will be touch dry after 15 - 20 minutes at room temperature and does not require a thermal cure. The full properties of the coating will be obtaine

Hi first DS65 version is a specific dilution for dispensing machine, in this case the typical process is following: application of the conformal coating extraction of solvent (low extraction power is better)2minutes and drying the drying can be done

Hola, I'm about to evaluate our BGA capabilities by using a dummy PCB+Components kit, I'll be evaluating solder paste, pick n place, reflow process & rework method. I have an idea of how to validate these processes. I'm planning to send different sa

If you want a step by step guide on BGA look at my NPL/IPC "Defect of the Month" video clips https://www.youtube.com/watch?v=MC4K0eSXH18 For other process issues there are also videos which may assist on other process issues like voids, solder ball

So far we have tried diferent date codes, solder pastes and PCBA models (same component used in different projects). We have also sent some components for plating analysis and we are waiting the LAB feedback. Additionally, we have tried components wi

I know it won't prevent this, but have you tried cleaning with a mix of screen cleaner and isopropyl alcohol in a 1/3rd - 2/3rd solution? We use this, put on by antistatic brush, and then using an air jet to blow it away. Afterwards, the PCB's look
