a process in which components are placed in an electrolyte solution in a barrel, then rotated or tumbled to provide an even coat--was discarded because the fragility of the components.
ECO provides both rack and barrel plating
services for parts up to 13 feet in length for low and high volume orders.
We've seen thin spots in barrel plating
consumed by solder, permitting laminate to outgas and create giant voids inside joints that have good looking top- and bottom-side fillets.
Increasing the copper barrel plating
thickness can improve the survival and long-term reliability of PCBs that will undergo the higher soldering temperatures used with lead-free solders, and this increased thickness will need to be specified by the designer.
At Chalcon's Walsall base, the installation of a computer-controlled automated zinc barrel plating
line had been completed this month, on time and to budget.
Babcock Wanson Thermal fluid systems are well proven as effective heating systems in a wide range of metal treatment and plating Applications range from pre-treatment, continuous and batch processes, barrel plating
, anodising, oven heating and general plant service such as makeup air heating and general heating needs
Past studies focusing on copper dissolution during PTH solder fountain rework using a SAC-based alloy highlighted concerns over the ability to rework PTH connectors without significantly dissolving portions of the copper barrel plating
For SnPb, the typical callout for barrel plating
thickness was 18 to 30 [micro]m.
This only applies to rack plated components, since the tumbling action of barrel plating
renders any other method of electrolyte movement unnecessary.
If the copper barrel plating
is not able to withstand this load, it can crack or tear.
The company's speciality is the fully automated decorative barrel plating
of items such as pen nibs, and protective corners, eyelets and other metal accessories for diaries, stationery products and leather goods.
When examining the cause of the residues on the capacitors, we found that the post-plating rinses after the barrel plating
process using methane sulfonic acid (MSA) as the primary plating chemistry were not neutralized or uniformly rinsed.
