I've never run D.I. water through an ultrasonic humidifier before. I think the reverse osmosis (RO) process removes more stuff (minerals and etc.) than the D.I. process does. My experience from using one in a home setting still tells me that is the

We agree with the points made by ScottE above. Additionally, most printers are not heavily loaded. So, you wouldn't have to buy another machine, give-up floor space, purchase and store peculiar tooling, etc. We think Darby does pin transfer. Maybe h

Dear All, I am a totally new to the SMT process. In fact, I just had an overview course regarding the whole process of PCBA manufacturing and I have know a bunch of questions in my head. Most of them are linked to the solder paste printing process

Currently, we are using fixed barcode scanners that connect to Cogiscan PFC box. The scanners are mounted using a flexible arm. The flexible arm is hard to adjust so that the scanner will be on top of the label every time it hits the sensor. I'm look

Hi All, Just wondering if anyone is placing 0201 components in volume. If so What pad layout are you using, i.e. pad size, shape and spacing. Also are you pads and fiducials solder mask defined or copper defined. Can you also let me know the rough q

We are not using SN100C in our reflow process but I know the type of flux made a big difference with our SAC305 solder. We started out using no-clean flux in our SAC305 paste and were having some issues. We then switched over to a water soluble flu

Here's what we hear you saying: * Trying to repair a printed circuit board assembly * There's a problem replacing a 57 pin, 20 thou connector * Can't get enough solder paste on the connector leads * Printing paste, replacing the connector, then reflo

Hi all, I used to be able to set a base program when optimizing in the MCS so that the new program would have the common feeders in the same location as the original... with a few exeptions. I'm trying to do this in the F4G and it is not working. I

You bet. Using a high temperature solder is a perfectly reasonable way the attach thermocouples. Just remember that the solder will not flow on the thermocouple. You need to use a solder iron to lay the solder over thermocouple to hold it in place.
