We have 250x340mm panel of PCBs. Stencil for glue would be 0,3mm with about 80 holes mostly for chip components. Our MPM printer at standard set, prints paste on 1 panel at 40-50sec. I need general information if printing glue is faster or slower p

We use a HEPCO model 3000-2 (hepcoblue.com) to shorten leads on various through hole components before we solder them on a pcb. You will have to verify they have a die that works with your particular LED module. If they do, this is what I would rec

Looking to find out what materials are commonly used for staking (aka. bonding) through hole components to the PCB in order to withstand vibration in a military (class 3) environment. Polyurethane coating would be applied after staking. I've found st

Smtnet, I am looking at pros and cons for automated soldering. The application is a simple multi pin through-hole soldering on a high volume manual assembly line. The goal was to eliminate defects associated with missing solder pins which goes undet

Universal Sequencer, VCD, Radial, or Unimod(DIP installer) machines! We only still have and run our Universal/Berg pinning machine. I can't say they will work any better than humans do as humans will have to run and maintain them though. We did get g

Certainly, machinery provides better quality for repetitive tasks than manual methods. In looking to improve the quality of manual methods, there are things that can be done. Some of those things have been discussed in earlier threads here on SMTne

Is there any harm in washing SMT soldered with NoClean paste? The PCA has some large thru-hole connectors that we would prefer to do as water soluble on out selective solder but the SMT consists of LGA's and other low parts that we would not be able

Hi, My name is Branden Spencer and I am a jr. engineer at TTM technologies. We are currently having and issue with our wave solder process. We are getting what looks like either solder dross or voiding in our solder joints (through hole and SMT). We

I have a pcb with 750 plated through holes that get Holtite sockets inserted into them. I have a method of pressing in 10 sockets at a time. However, when we are done, the board has bad warpage on the X and Y axis. Does anyone out there have any t

Has anyone else had failures with Leds from EOI? The part number is EOZ-ZARNCD0-DG. We are using a lead free no clean process using SAC305 solder. These are thru hole parts and our max temp is 244 for 3 seconds. Please if anyone else had issues
