...and it should also be easy for the SMTnet to set a max pixel size and format types for the allowed attached pictures or files, so it would not sink the servers. Otherwise rejection of the attachement(s). If people are concerned with hidden trojans

Turning off the grid-lok is not an option. I have used the hand inserted tooling in the past..It takes too long to set up and it does not accomodate warped boards. So I am I safe in saying that there is not much I can do aside from change my board d

When no-clean flux and no-clean soldering first came out in the late 80's / early 90's, there were lots of White Papers written about conformal coating adhesion and no-clean flux. I'm pretty sure all CC's will adhere to today's chemistries. To be o

Thick, hard conformal coatings of acrylic, urethane and epoxy have a well documented history of causing solder joint cracks and breaking glass/ceramic and other brittle components. Dissimilar expansion and fairly high surface bond strengths of the ma

Hi all, just wondering what type of brushes you all are using to manually touch up/apply your conformal coatings? We use an solvent based acrylic and do minor touch ups as they are processed. Occasionally we will have a bristle or two come off the
