Hello all, We use pressurized air from a blower to blow off excess water from our pcb assemblies after wash. I'm concerned that this could potentially cause esd damage to sensitive assemblies. Is anyone aware of a device that can correctly ionize the

Hello Kris, No, it's not necessary to have a nitrogen tunnel setup. A nitrogen tunnel allows a process to go the extra step in providing higher quality through less defects. I can't really speculate on it's use in contract manufacturers mainly becaus

Can anyone who has DEK Horizon's 2D Advance Package System explain how does this below feature works? "Automatically triggered recovery sequences" Does it mean that operator need not be there to press any button to clean and recover a print if the

Hello, I would like to ask for cooments/advices about the inspection of small solder deposits inspection (aprox 4 mills). We tried with X ray and Scanning acoustic microscope but it looks like due to the small size, we could not be sure to get all t

We are investigating a system, using 2-D matrix code, that will identify and track every PCB throughout our factory, starting from bare board. As a low-medium volume manufacturer, would labels or laser marking be more cost-effective? How difficult is

Hi I had to poke around awhile to see what you meant. I think you were at an advanced level where IF he knew the MSL ratings of his devices he should constrain his profile within the component mfgs tests for exposure to various profiles, or at leas

Hi all, Now there's another question regarding lead free I want to ask. Suppose I want to qualify a SMT product for lead free, do I need to use a lead free solder paste or any other normal solder paste will do ? What are the impact of using a lead

This is an old topic, but keeps coming up. Solderability and reliability issues with SMT gold plated terminations when used with tin/lead solder paste/hassle finish PWB. I need to know which standard (mil, IPC, J-STD??) tells you all about the probl

Does anyone out here remember the Advanced Research Technologies ISIS machine? It was fantastic at defect detection by seeing hotspots on difficult to troubleshoot boards. I know that Photon Dynamics bought out the ISIS technology from ART, but the t

From the equipment side in the last 10-15 years ? I suppose the whole push toward modular machines. Less floor space, increased capability in a single platform - speed of a traditional chip shooter, common spares, blah blah blah. Some of the recogn
