Welding Equipment Control Board Assembly

NOTICE TO BUYERS:

We are a Professional Electronics Contract Manufacturer (EMS). We do NOT sell retail or off-the-shelf ready-to-ship replacement boards. All products shown are custom manufacturing cases protected by client NDA. To get a formal quotation within 24 hours, please provide:

1. Gerber Files (RS-274X)
2. Complete BOM List (with manufacturer part numbers)
3. Estimated Order Volume (Prototype or Mass Production)

Board Profile:

• Configuration: separate control board and power board, or combined
• Laminate: high-TG FR-4; aluminum base for power sections
• Layers: 2-6
• Copper weight: 2oz - 4oz (heavy copper for current capacity)
• Board thickness: 1.6mm - 2.0mm
• Finish: lead-free HASL / ENIG
• Assembly: SMT plus selective through-hole for power devices
• Control supply: DC 12V / 24V
• Standards: IPC-A-610 Class 2 or Class 3

Power Stage & Materials:

• IGBT / MOSFET gate drive with opto or digital isolation
• Thermal vias and copper pours beneath power devices
• Heatsink mounting patterns machined to drawing
• High-current traces and busbar interfaces
• Conformal coating for dusty workshop environments

Typical Equipment:

• Inverter arc welders (MMA / TIG / MIG)
• Resistance spot welders
• Battery tab and pack welding machines
• Automated welding cells and fixtures

Engineering Strengths:

• Heavy-copper and high-current layout experience
• Isolation and dielectric withstand (hipot) testing
• Thermal design verified before production release
• Fabrication, sourcing, assembly, and load testing in one facility
• 24 years of industrial electronics manufacturing

FAQ:

Q1: Is this board sold as a spare part?

A: No - it is a manufacturing case. Every board is built from the customer's own data.

Q2: Can you process copper heavier than 4oz?

A: Yes, heavier builds are reviewed case by case.

Q3: Do you perform hipot and load testing?

A: Yes - dielectric withstand and functional load tests can be included.

Q4: What do you need to start a quotation?

A: Gerber (RS-274X), BOM with MPNs, and expected order volume.
