Quadstar 100 with vision and dispenser

Electronics Forum | Sun Mar 22 14:51:35 EST 1998 | Martin Plourde

I'm looking for a Quadstar 100 with any top vision as well as a glue dispenser. Must have both features or I am not interested. I've located many Quadstars 100 with either features but my customer wants both absolutely Regards, Martin Plourde (514)

Solder bridges on TQFP 100 part

Electronics Forum | Wed Aug 07 01:41:27 EDT 2019 | orbitcoms

Hi I am having trouble getting solder bridges on TQFP-100 (0.5mm pitch) components. The boards are pasted on semi-auto printer using laser-cut 0.12mm stencil and SN63 NC257-2 T4 paste. The components are placed using Samsung CP40LV and tghen reflow

Anyone using a No-clean solder paste on a pcb with a 100 Mbps Ethernet chip? Will the residue cause any signal degradation? Any issues with a no-clean solder paste and 1000 Mbps Gigabit Ethernet? Device: National Semiconductor DP83848 10/100 Mb

How do you normally solder it?

A water soluble solder paste (AIM WS483), reflow and wash. We are considering using AIM NC254 No-clean solder paste to eliminate the wash step.

I would think if the product can take wash, it could take no-clean. Unless it has sensitive devices susceptible to leakage.

We built tens of thousands of boards with transeivers on them with a no clean process.Never had any problems with the flux residue in relationship to board performance.

Residues from different no-clean fluxes produce different levels of variation in RF circuits. Some no-clean fluxes work fine. Following this, a no-clean flux can produce different levels of variation in RF circuits depending on the process setup.

SMT line expansion - new oven and selective solder

Electronics Forum | Sat Feb 22 11:37:00 EST 2020 | kylehunter

Hey all, I've made a post in the past about us expanding to a new space, but I wanted to do a new post with specific questions. We currently have a DEK 265, Phillips Opal Xii, and a Heller 1500. Our main reason for expanding is to have a lead-free

NADCAP and thermocouple calibration

Electronics Forum | Thu Aug 08 13:09:38 EDT 2013 | cyber_wolf

Hege, there is no actual calibration of the thermocouple itself. You can however verify that they read correctly. Heller sells an option on their reflow ovens specifically for this purpose. I hoping that someone chimes in here that is NADCAP certifi
