Peter, Based on the images, it looks the HASL is too thin. I have seen this a few times when the pcb supplier uses too aggressive of a process to remove the solder. This can lead to oxidation of the underlying copper. An XRF of a pad that won't take

It is recommended that the thickness of the stencil of 0.1mm, the steel mesh should be partially nano-coated. It is best not to dry easily, and the particles are not easy to be too large. I have tried ALLPCB for this kind of BGA in the past and they

I'm putting together a spec for testing solder tips for resistance, voltage leakage, and temp tolerance. I've found solid numbers for both max acceptable resistance and voltage leakage, but nothing for max temp tolerance. Anyone have values they're

Hi, I am looking for a Solder jet supplier. Micronic does not support my small dot size LEADED solder paste. I can not use stencil print because my substrate is fragile. I need a run rate of 10,000 dots per hour and 99.99 % dots +- 10% volume. Equip

If it is "wondermask" made by Techspray, it is supposed to be water soluble. It being overcured (we have experienced this before), water will not touch it. We used acetone which softened it up to remove it with an orange stick. We apply it ourselves

I think you'd better create the BOM list first and clarify what kinds of components you want, then you can contact the assembly supplier for quotation, just remind them to use the cheapest one, many Chinese supplier can offer very attractive price fo

Have you run some simple placement test yet? Use double-sided tape on the solder sample, run different size of components to see if all or certain size part are placed off; best with different rotation angle too. Chances are nozzle(s) or even shaft
