Is HASL a Good Choice for Surface Finish?
We are using a lead-free hot air solder leveling board finish. Our boards have bottom-terminated components. Is this the best choice? The Assembly Brothers, Jim Hall and Phil Zarrow, discuss this scenario and share their own suggestions and recommendations.
Board Talk
Connector Bowing During Reflow Process
I have a connector that is bowing during lead-free soldering. When the connector is put through an oven on its own no bowing takes place. What is causing this?
Board Talk
Can Solder Mask Be Considered an Insulator?
Is solder mask considered an insulating material and not a defect if proven the solder mask has dielectric withstanding voltage greater than 500 volts? Is solder mask considered a durable insulator over time in harsh environments? The Assembly Brothers, Jim Hall and Phil Zarrow, address these questions.
Board Talk
Long Term Component Storage
We need to store SMD components for at least 10 years. What do you recommend for a humidity and temperature settings?
Board Talk
What Causes Solder Balls During Hand Soldering?
We have experienced solder balls during automated reflow. Now we are finding solder balls during the hand soldering. Phil Zarrow and Jim Hall, The Assembly Brothers, offer their own suggestions and recommendations for eliminating solder balls.
Board Talk
Has My Flux Expired?
What specific attributes occur in an expired flux? How do you know if a flux is bad and shouldn't be used? Are there any simple tests?
Board Talk
Wet-Based vs. Dry-Based Cleaning
For automatic under-stencil cleaning there are many cleaning methods including dry vacuum cleaning, wet dry vacuum cleaning. What factors should we consider to select wet based cleaning versus dry based cleaning? The Assembly Brothers, Jim Hall and Phil Zarrow, discuss this scenario and offer their suggestions.
Board Talk
Processing Circuit Boards with BGAs On Both Sides
What is the best way to process a 30 mil circuit board assembly that has micro BGAs that need to be soldered to both sides?
Board Talk
Seeking Alternatives to Solvent Cleaning
We are using a mix of trichloroethylene and IPA for cleaning in the ratio of 10 to 90. We are looking to eliminate the use of trichloroethylene. Phil Zarrow and Jim Hall, The Assembly Brothers, offer their suggestions.
Board Talk
What is the Life Span of a Profile Board?
What is the life span of a profile board? How many times can I use one test board to profile a reflow oven before throwing it away and why?
