An extensive range of finished PCB thicknesses can be accomplished with the combination of different core thicknesses and sheets of prepreg. However, the variety of laminate thickness options offered to our customers are range from 0.008 inches to 0.240 inches and they include 0.2 mm (0.0079 inch), 0.4 mm (0.016 inch), 0.5 mm (0.020 inch), 0.6 mm (0.024 inch), 0.8 mm (0.032 inch), 1.0 mm (0.04 inch), 1.2 mm (0.047 inch), 1.5 mm (0.062 inch), 1.6 mm (0.063 inch), 2.0 mm (0.079 inch), 2.3 mm (0.091 inch), etc.
We strive to provide multiple laminate options to ensure a quality product is delivered to our customers. We normally use the laminate thickness as per your specifications and needs. Though, our team offers a standard thickness of 1.6 mm (0.063 inch). Sometimes, the circuit board core thickness and soldermask coating must be considered for trace impedance. When computing impedance, the consequences of conformal coating must be taken into account as the circuit boards are usually covered in soldermask. In general, soldermask decreases the impedance on thin traces. The soldermask has considerably less effect when the trace thickness increases.
Circuit board finish differs in rates, availability, serviceable life, consistency and assembly processing. As each finish has its individual advantages, product, the procedures, or setting will define the appropriate surface finish that is suitable for the application. We recommend our users and the designer to constantly coordinate with us for selection of ideal finish for the required product design. This will ensure you have better prices for the end product delivery.
Our intention is to give quality services with competitive prices to our customers. We many times devise the effective cost structure for our buyer so as to have an overall reduction in the prices and offer superior services as compared to other electronic contract manufacturers. Sometimes prices vary with circuit board thickness but this again depends as per the customer specifications. If the buyer selects a non-standard PCB thickness, then the cost will increase because these are more costly than standard materials.
