5 vs 8-Zone Ovens
5 vs 8-Zone Ovens
We are setting up an assembly line for small line production. We prefer to purchase a 5-zone oven but our concern is that five zones may not be enough to ensure a reliable reflow process compared to an 8-zone oven. Jim Hall and Phil Zarrow, The Assembly Brothers, share their insight.

Simple Test for Flux Penetration
Simple Test for Flux Penetration
What is a good test for flux penetration through plated hole barrels on plated through hole circuit boards? A simple method is offered.
Board Talk
BGA Components and Coplanarity
BGA Components and Coplanarity
We have a PCB with a HASL surface finish, the assembly includes a 256 ball BGA. The component balls are .6 mm pitch. Is coplanarity a concern? Jim Hall and Phil Zarrow, The Assembly Brothers, answer this question.

What is Solder Paste Working Life on a Stencil?
What is Solder Paste Working Life on a Stencil?
Our solder paste has an exposure life of ten hours. After ten hours of operation do we need to remove all of the paste on the stencil and scrap it? The Assembly Brothers, Jim Hall and Phil Zarrow, share their experiences.

What is Ideal Humidity for Final Assembly?
What is Ideal Humidity for Final Assembly?
What is ideal humidity within a final assembly facility? No soldering involved. The facility is used for final box build.
Board Talk
Step Stencil Setup
Step Stencil Setup
When shifting from standard solder paste stencils to step stencils, should we change the pressure or attack angle? Phil Zarrow and Jim Hall, The Assembly Brothers, answer this question and share their own experiences.
Board Talk
Should Apertures be Home Plate or Inverted Home Plate?
Should Apertures be Home Plate or Inverted Home Plate?
Should stencil the aperture be home plate or inverted home plate? You know the performance difference between the two types. Which one is better?
Board Talk
Acceptable Rate for Head in Pillow?
Acceptable Rate for Head in Pillow?
We have rejects in 2-3 per 15,000 PCBs that look like Head in Pillow. Should we tinker with the reflow process, or is this reject rate acceptable? Jim Hall and Phil Zarrow, The Assembly Brothers, share their experiences.
