Through Hole Double Sided PCB Board FR4 Material Two Layer Design OEM Service

What is FR4 Through-hole Double-sided Board PCB?

A double-sided through-hole PCB features conductive copper circuits on both sides of the board. These layers are interconnected by Plated Through-Holes (PTH)—holes drilled through the substrate and chemically plated with metal.

Main Features of Double Sided PCB:

1.Dual-Sided Copper Cladding

2.Plated Through-Holes (PTHs)

3.Balanced Performance-Cost

4.Moderate Component Density

5.Flexible Routing

6.Wider Application Adaptability

Customization Double Sided PCB Service:

Please send us your:
1. Gerber files (RS-274X)
2. BOM (if PCBA needed)
3. Impedance requirements & stack-up (if available)
4.Test requirements (TDR, network analyzer, etc.)

Noted:Normally,Gerber files includes: PCB types,thickness, ink color, surface treatment process, and if SMT processing is required, you can provide a component BOM and reference designation diagram, etc.

We’ll reply within 24 hours with a free quote, DFM report, and material recommendation.

The manufacturing difficulties of through-hole double-sided PCBs:

1.Drilling requires high accuracy to create clean, burr-free holes that align perfectly between layers, as misalignment can lead to broken circuits or short circuits.

2.Via hole metallization demands consistent deposition of conductive copper (typically 20–25μm thick) on hole walls to ensure electrical continuity and withstand thermal stress during soldering; inadequate thickness or voids can cause failures.

3.Registration control must keep alignment deviations between double-sided graphics and via holes within ±0.075mm to prevent connectivity errors.

4.Etching and plating processes need tight control over line width/spacing tolerances (±10%) and uniform surface treatment (e.g., HASL, ENIG) to avoid over-etching, residual copper, or poor solderability.
