Fabricant et assemblage d'échantillons de PCB - Service à guichet unique

Échantillon de PCB - Vérification des circuits imprimés. C'est une partie électronique très importante, et le support PCB pour les composants électroniques est le fournisseur de connexions électriques pour les composants électroniques. Parce qu'il est fabriqué par impression électronique, il est appelé un circuit imprimé «d'impression».

L'échantillon de PCB est un essai moyen avant la commande par lots, le projet principal est l'ingénieur PE conçoit le circuit et termine toute la disposition du PCB, le client passe la commande à l'usine et essaie une démonstration. Avant que le concepteur ne termine tout le travail, confirmez et testez, toute la démo qui appelle «Sample».

Moreover, this demo has no MOQ (Minimum Order Quantity). If customer final needs to do PCB assembly. KINGFORD advise your first demo is more than 10pcs because the quantity more then 10pcs we can do the assembly by Hi-speed Mounting Inspection. The final result is better than DIP.

What information need before “Take PCB Sample”:

Firstly, materials: please explain what PCB panel materials you need? The common texture is FR4. Its main materials are Epoxy resin stripped fiber cloth board.

Secondly, layer: How many layers you need?

Thirdly, the color of Solder Mask: the color base on client real requirement. It has green, blue, black, red and yellow, etc. The most common need is Green.

Fourthly, the color of Silk-Screen: The color of character and frame on PCB. The common style is white.

Fifthly, copper thickness: We usually scientific calculation copper thickness via PCB circuit current. The thicker the better, but more expensive, so that need to a reasonable balance.

Sixth, whether the through-hole covers solder resistance: Resistance welding is insulation over the hole. Otherwise, it is not insulation over the hole.

Seventh, surface coating: SMOBC & HAL and Gold Plating you can choose.

Lastly, quantity: how many pieces you want to try first order?

Remarques:

Firstly, Please care should be taken in the selection of proofing quantity to effectively control the cost.

Secondly, Special validation of device packaging to avoid failure of proofing due to packaging errors.

Thirdly, Conduct comprehensive electrical inspection to improve the electrical performance of the PCB board.

Enfin, veuillez effectuer une mise en page complète du signal, réduire le bruit et améliorer la stabilité du PCB.
