Why panelized Nelco laminate pcb is important？
The miniaturization of electronic products requires a similar reduction in board size. Therefore, you must do array for Nelco boards when determining initial size, especially if you do not want to interfere with their intended function and performance. It not only helps maximize board yield per PCB panel, but also helps reduce board cost per PCB.
Board panelization becomes critical when you define the available surface of the board where you can easily route the board (place components and draw copper traces). For example, typical PCB boards have panel sizes of 12 x 18 inches and 18 x 24 inches.
However, since the available surface usually proves less in the case of one inch per side, the available surface becomes 10 × 16 inches and 16 × 22 inches. In addition, multilayer paneling requires a minimum spacing of 100 mils.

You can choose among the numerous lamination procedures to apply Nelco laminates on your printed circuit board.
It is important that you consider the fact that the type of lamination procedure you choose will depend on PCB types.
Here are the main types of lamination procedures that you can use to apply Nelco laminates.
· Multilayer Printed Circuit Board Lamination
This is the lamination process of a circuit board that consists of different layers stuck together to form multilayer PCB.
You will bond these layers using Nelco laminates by subjecting the internal layers under extreme pressure and temperature.
You will set the temperatures at about 375 degrees Fahrenheit and the pressure between 275 to 400 psi.
You will implement this procedure when you are dealing with or laminating photosensitive dry resist materials.
As soon as you complete that, you will cure the Nelco laminate, release the pressure slowly and the cool the laminate.

What is the Step by Step Process of Applying the Nelco Laminates?
Well, with the information on the different techniques of laminating PCBs, you can proceed to applying the Nelco laminates.
In this case, we are going to use the multilayer PCB approach since Nelco laminates are best for multilayer PCBs.
Here is a step by step process that you should follow when applying the Nelco laminates.
Step One: Preparation of the Boards.
You will begin the whole process by preparing the circuit boards that you would like to laminate.
Preparation in this case means copper etching or tracing of the circuit boards before lamination.
As soon as you complete that, you will proceed to the lamination procedures of the PCBs.
Step Two: Lamination Process
Here, you will place the Nelco laminates in between every layer of the printed circuit board.
After that, you will place the multiple layers under extreme pressure ranging between 275 to 400 psi.
In addition to that, you will also apply extreme temperatures of about 375 degrees Fahrenheit.

You can place the multilayer PCBs inside an oven under extreme temperatures as well as pressure.
Here, the lamination materials will flow and bond all the PCB layers together.
Step Four: Cooling Process
You will complete the whole process by cooling the PCB laminates s you release the pressure slowly.
The cooling temperatures will vary according to the type of PCB laminates and size of PCB.
Do You Supply Flexible Nelco Laminates?
Yes, we also supply flexible Nelco laminates according to the request of the customers.
These are thin and foldable Nelco laminate that allows the printed circuit boards to bend without affecting electrical continuity.

· Blind Via Boards
In this case, you will glue two subparts together where subparts are on the outside of the Nelco laminated PCB.
You might have drilled plated through holes in the subparts as well as microvias to complete the connections.
You also have the freedom of combining all the three types of architecture in sequential Nelco lamination.
What are Some of the Problems that Would Affect the Nelco Laminates?
You always strife to get a beautiful printed circuit board with all the factors remaining constant.
There are particular situations when this may not be possible due to particular lamination problems.
Here are some of the problems that you might experience during Nelco lamination processes.

In this case, you can experience cases where the copper foil separates from the resin.
Apart from that, you may experience cases where the resin separates from indium within the internal layers.
In addition to that, there are cases where the blisters within the resins separate from one another.
This can happen due to pressure during the drilling process or mismatch during the assembly and routing processes.
You can identify such a problem by troubleshooting the whole device since it appears after completing the job.
· Line Width Issues
Here is a situation where there is an exposure of the sidewall of the photoresist that protects the copper.
You will realize that this problem exists when more copper dissolves away through the copper etching process.
· Surface Prep Issues
You may experience a couple of issues with the surface prep such as dents in copper foils, and particulate matter.
It will end up eating more than 10% of the copper during the etching process thus causing a great loss.
· DES Process Defects
In this case, you will have an exposure on the resist before you commence the etching process.
It may lead to losses on the circuit traces thus leading to open circuits and effecting the entire lamination processes.
