I like what you're doing. 20 years ago anyone, hobbyists and tiny garage-shop companies could create electronics devices just as sophisticated and cool as big corporations. Today, SMT has largely trashed the creativity (and competition) that existe

I think most have summed up the first pictures also is the drillng looking like it is misregistered as well. Better to do a solvent test to determine resist cure not the old stuff the newer chemicals show under cure problem much better. Try your st

It has been my experience that when all conditions are as they are supposed to be there should be zero or very little deflection. When you start placing components with pick and place equipment that does not have a Z pressure sense, you run the possi

Some PCB's manufacturers are now able to fill the hole and then re-metallized the pattern in order to obtain a final soldering surface perfectly flat but with an electrical connection under. This of course increase the price of the pcb but avoid any

What are you placing on this equipment? If you are placing flip chips, you need to have a glass plate test system to verify your machine is accurate and repeatable. If you purchase new equipment and plan to place flip chips or ultra fine pitch, it

We are going to try out a PCB manufacturer that has an Alpha Level for ensuring a flat finish on the PCB's. I am interested to know if anyone has and experiences, either good or bad on how boards treated with this process are to assemble. Is there a

SMT chip processing short-circuit bad phenomenon mostly in the fine pitch IC pins, mostly in the 0.5mm and the following pitch between the IC pins, because its spacing is small, improperly designed template or printing a slight omission is very easy

We've had much trouble with flex circuits. As previously mentioned, you must have local fids for the board or the BGA itself (if panelized). Other troubles we experience are drilled holes for pinned connectors. Unless the PCB manufactur has some w
