As the technology has changed towards surface mount, so has the applying adhesive. In the past clinching parts would have knocked off SMD parts, but no that has all changed. So applying the adhesive via screen print is common and any thru-hole part

We evaluated several rework machines a few years ago and decided on the Finetech CRS-10. It outperformed the Airvac DRS25 machine. We didn't bring in the Focal Spot because it uses IR. The Focal Spot System does not have a solder removal option and

We are experiencing a high incidence of what we call "black barrel" (to differentiate from black pad) with multiple contract manufacturers and PCB vendors. The PCBs are ENIG and during wave solder (SACX-0307) multiple thru-hole components are seeing

Hi, You can go a long to answering that question yourself - what do you need to see? If you are lookig for the normal stuff like bridging, opens and voids you dont need anywhere near 130-160kv. I have just completed the same excercise and we have s

what is the technology? Is there fine pitch, double sided, number of layers, lead free? If the pcbs are not of the highest quality you may be set up for failure with no clean process. Couple things to look at is your paste flux content versus medal

Hello, As our company has begun doing an increase production of contract manufacturing I have seen more and more designs with the 0402 pad layouts that are smaller (.015 in width) than the component. Also there is only a .008 longer than the 0402 p

Hello, I am a new comer and working for a contract manufacturer as an engineer. My company handles many prototype jobs from new customers, and most customers do not give us CAD file. We receive Gerber, XY and BOM from customers. So every single job

Hi, I work for a Cable and Harness contract manufacturer. I have started offering soldering classes to some of the employees but because we do not build circuit boards, I don't have any material for them to practice with. I was able to get a few ba

Yes agreed you're 100% right on that. You always want to go for the full CAD file or the XY rotation file first. But like a lot of contract manufacturers and some OEM's find they have to work with Gerber only data for certain projects. The Unisoft s
